I hope teens and college students watch your videos forever and every year so that you can get that bag, you deserve it IDK how many careers you have saved
yep college is about pumping people out and hoping they teach themselves or they fail to retake. my ochem professor makes 150k a year and is one of the worse professor I have had yet.
@@89TNash When I took calc 4 class, the prof was polish guy with a very thick polish accent. From the day1 90% of class started complaining about prof that they can’t understand anything. In the end those 90% ended up with an avg D, majority failing, while the rest got A. Thing is, for those 10% it was a breeze because they focused on learning. So in the end who cares if he’s earning 150k, you’re paying a lot more, so why not enjoy the process and focus on learning and not on teaching style, are you afraid its going to toughen you up? You learn to accept adversity, whether it be in teaching style or anything, you’ll have a much easier time, adapt easily, and also enjoy the process. But I can understand your pain bro, just suck it up and focus on the bigger picture, i mean it is your money at the end of the day 🤷♂️
Great video! Thank you for that. Question: are there nuclei that flip to B-spinstate when subjected to a magnetic field, without the need for RF energy?
Just a wild guess, but I think they only do when the radio-frequency hits them. Atoms in general can only absorb discrete packets of energy, so the nuclei can only flip entirely or not at all (and not, say, half way). If they flip, they have higher energy than the unflipped ones, and want to go back to the lower level of energy (where they are aligned with the external B) and by doing so they release the same radio-frequency they had absorbed. The NMR apparatus registers this last radio-frequency, which is different for every element
Also you write a 11T field. That's very high for an MRI but is that a practical level for a momentary electromagnet in just spectroscopy? or is that just an arbitrary value for the calculation.
I ran an NMR spectrometer 20 years ago...... main thing about it is the constant fear it might leak it's liquids that should be gases......I still don't quite get what they do.......but it's powerful magic that kills mechanical watches
Note: The nucleus only possesses overall ‘spin’ if only the NUCLEON number is odd. If both the proton number and neutron number are odd, the nucleon number will be even and the nucleus cannot be used for NMR. Great video nonetheless. Thanks.
Wow. Most Indian videos confused me. Urs is a good one Can anyone answer me why does proton acquire with or against the magnetic field direction? I mean what is the reason for attaining alpha or beta?
Hello everyone! I have a problem with interpretation of nmr spectrum. I think I use coupling constant incorrectly. How indicate organic structure coresponding by using nmr spectrum?
You have it wrong about the magnetic property of the nucleus, is not because of the motion. The nucleus is not moving has the electrons do. Is given precisely by the property of the spin itself, up and down cancelled each other. Odd numbers give magnetic moment.
saying that the mass number being odd is a little misleading. the number of protons and the number of neutrons may both be odd then the mass number will be even
I hate this so much. I was doing *so well* in my Organic Chem class this semester...until this NMR mess came along. Now my A is probably gone. Still going to need to figure it out over the summer. I have to take the second level of ochem next semester and I'm sure it won't be kind enough to never remind me this exists.
Good video although I'd recommend prepared images. Writing in real time is unnecessary. Like hand writing a book while someone is reading it. Chalkboard teaching is not efficient. And making a point out of what mega means, may be unnecessary at this level :) The frequency of 500MHz, does that limit resolution? I'm thinking in terms of MRI and such. 500MHz is very large waves or is there a way around that? I suppose you select the location by gradient and the 500MHz is just the carrier, not resolution limiter? Meaning you must scan voxel by voxel, ruling out a global mode instant scan.

I have been confused about this topic for days. Your explanation and diagrams are so great that I finally understand NMR. Thank you
I thought I'd never understand this- you made it SO simple. Thank youuuuuuuuuuu!!!!!!!!!!!
Thank you for all your work. I am a Msc degree student and cannot be more grateful for everything you are helping me with
How did your studies go?
you are amazing. my 30 pages of reading and professor could never.
Basic introduction? More like “Beautiful instruction!” 👍
Dog when I get this money right I promise I'm sending you a generous ass contribution
Did you get that money right?
@@violahero4life yes sir sent that generous contribution too
I love this update. Best of luck with your career!!

Finally, a solution!!
After weeks of struggling 😭 😭
Thank you!!!
Basics of NMR explained in a clear and concise manner
omg i needed this, i didnt even watch the video yet
Best Chem tutor online. Great Job
hey man, you're a cool guy, thanks for learning me this and making this easy
Thank you for Ur time and explanations 🙏🤗.
i was hoping to god he had a video on this. Bless!!!!!!
You need a bloody award! So succinct.
who's using this during the pandemic
6 months later
we're still in the pandemic🤦
and we're still using this
7 months later

A year later and we are still in the pandemic XD
I really appreciate your videos. It made me understand what I couldn't grasp for hours. Go bless ya
One ov the greatest tutorial explanation ever🎉
This was really helpful thank you. Can you put this series in an organized play list
Do you think you could do more videos on NMR spectroscopy - videos on the magnetogyric ratio, vector model, fourier transform NMR and so on?
Great insight in teaching skills. A good teacher
Dude, you deserve my professor’s salary.
God bless you abundantly Organic Tutor
Great intro. One nucleus, two nuclei.
They should hire you to teach teachers this is incredible work
Amazing tutor 🙏
Wow. If only you had uploaded this video like 8 hours ago...
Great explanation! Thanks!
The only channel I watch the ads in full
thankyou, do you plan on making a discord maybe? it's a great way to communicate with your viewers
Thanks to u for three things:
Black background
Calm voice &
Wise pauses in videos.
Your channel is worth of getting at least 10 million subscribers 😊😊
Great video! Thank you for that. Question: are there nuclei that flip to B-spinstate when subjected to a magnetic field, without the need for RF energy?
could you do a video about realxations(like spin-lattice relxation)?
Too good Explanation.
thank you a lot but please can you make a video on transpositions ( organic chemistry )
thanks for being amazing dude
Greate explanation! Thank you very much! Is there a formula for calculating gamma as well?
Wonderful Wonderful Wonderful...How good is he...
But who is this guy that knows almost every subject of science?
Thank you!
Nice video and well though out.
very interesting and very well explained! thanks
Ah, our wizard explains the Black Magic. Please accept my thumbs up in gratitude.
We need teachers like you
Thank you once again.
You are too good. Thank you very much.
great video. Thank you!
this was really helpful
Ur everything to me tbh wherever u live
unique explanation ,
Why does some of the nuclei move in a direction opposite to that of the applied magnetic field?
Just a wild guess, but I think they only do when the radio-frequency hits them. Atoms in general can only absorb discrete packets of energy, so the nuclei can only flip entirely or not at all (and not, say, half way). If they flip, they have higher energy than the unflipped ones, and want to go back to the lower level of energy (where they are aligned with the external B) and by doing so they release the same radio-frequency they had absorbed. The NMR apparatus registers this last radio-frequency, which is different for every element
Thank you alot
Can deuterium show spectroscopy? I mean it has just 1 proton and 1 neutron, so mass is 2 but there is only 1 proton!!
I hear the words “in this video” and I already know everything’s going to be okay
Thank you so much!
Love your video!
thank you for these
Very useful. Thanks a lot
Also you write a 11T field. That's very high for an MRI but is that a practical level for a momentary electromagnet in just spectroscopy? or is that just an arbitrary value for the calculation.

Great video nonetheless. Thanks.
Sorry but this is not right. If both proton and neutron number is odd, the nucleus may posses a whole integer spin eg 14N or 2H
The GOAT. !
Thanks man🎉
Nice video
So at 8:54 you got gamma, but I am confused on where you are getting it from
In 8 minutes you explained what the teacher couldn't in half a year
Fan of yours
Wow. Most Indian videos confused me. Urs is a good one
Can anyone answer me why does proton acquire with or against the magnetic field direction? I mean what is the reason for attaining alpha or beta?
I think it's because they're at different energy levels- one is weak enough to have the spin flipped by magnetic field and the other is not.
Also the local magnetic field
Hello everyone!
I have a problem with interpretation of nmr spectrum. I think I use coupling constant incorrectly. How indicate organic structure coresponding by using nmr spectrum?
Where did you get that gamma? Its constant or what?
You have it wrong about the magnetic property of the nucleus, is not because of the motion.
The nucleus is not moving has the electrons do. Is given precisely by the property of the spin itself, up and down cancelled each other.
Odd numbers give magnetic moment.
How can a proton in the nucleus spin? Doesn't protons and neutrons are held together in the nucleus...?How could a proton see spin about is axis?
Will you create video on probability dice problem?
go watch bozeman...he has few vids on it
Hnnng thank you so much!!!
Thank yu

How do we know these proteins have an odd number of protons or neutrons?
Are you asking how many protons / neutrons in a given nucleus?
Raghu A I think that’s what I was asking, haha
Now that it’s four months old I’m not really sure but that seems to make sense.
h+ producing B has nothing to do afaik
