Fantastic Explanation and ur style to do it is Splendid👍 I Understood very well about this topic. From Graduation to PG my Scores in exams are majorly dedicated to you. Thank you very much sir ☺️🙏 Keep it doing this Great work .
tomorrow is my exam and im here because of this lecture . its too good instead reading this one in book thanks a lot brother. too helpfull foe bsc final year students thanks once again
I am highly appreciating suman sir.actually he is wanting to teach us the basis of NMR spectroscopy. to persuade the basis,he took those example.if anyone do not know that C-H-C would not be formed, he has no meaning to understand the NMR spectroscopy. I earnestly request those critics to know basic chemistry and then to criticize. hats off suman sir.
Seriously you are a degree saver😅 you explain in such a great manner, that no one else could explain a topic that clearly 😇 watching your videos since I was in my 1st year (now I am in 3rd year), you cleared many concepts in microbiology, chemistry.... I mean uts a headache toh read different books for 1 topic... You made it really easy for students like us.. Thank you so much sir🙏🙏🙏
I have discovered this channel after my 3rd year of BSC life, pharmaceutical analysis topics couldn’t explain more precisely than this, very thankful to you sir💯
NMR spectroscopy is sure an interesting technique and as a core biology student I have to work hard to understand this topic well. This a the first lecture which I watched completely on this topic as I understood the lecture slowly.
Thanks sir .. I have been studying this nmr spectroscopy for last 2 years.. but I got a basic idea about it only now after hearing your class... Really thankful to you
Wow!!!! this what we called FANTASTIC,,I experienced a lot of problems on NMR but now I know something and i will keep watching it over and over...Thanks Sir
Thanks a lot .sir...🙇🙇🙇🙇u make it easy .. umar ke hissab se professor bhi kar na paye woh apne bhot aasani se kar diya ...great inspiration to young generation. .apke jisa her koi sikhata tho aj u tube pe na hote hum👍👍👍👍👍👌👌
My viva is going to start in about 30 minutes from now and here i am , just watched the complete video and didn't tackle anything too hard to understand. Everything is easily explained . You saved a ton of my time. 👍
When I'm in a state of confusion, usually I come to take your lesson to have a basic and very vivid understanding of the topic. You're such an amazing teacher, keep doing it bro.
Dear sir, NMR was a very difficult topic for me to understand. But luckily I saw your lecture and it could teach me what NMR basically is...I have attended many lectures on NMR, but nothing worked...and I feared the topic. But now I am confident that I know NMR. thanks a lot sir.
Dear Suman..one thing i have noticed that what u r saying is, in the presence of external magnetic field applied by the machine the spin of protons oriented in alpha state that is most stable state and then we will apply some electromagnetic radiation to convert in beta state..I think that is not true..In the absence of magnetic field(under the earth magnetic field) the magnet are randomly oriented in any direction. But when you apply external magnetic field by NMR machine it will oriented in two direction alpha and beta state..and since accorting to Boltzmann distribution law the molecules in alpha state is little more then beta state. When we will applied radio frequency the alpha spin state flips ito beta spin state and the process is called as resonance.
Thank you so much... You are doing a really great work... You provide free lecture and get our concept clear... You help so many students... Thank you so much... You give so simple and clear lecture on every topic.. Thank you once again... I generally do not comment on videos on RUclips... But you are doing a great work which i must need to appreciate ...
The only thing that ticks me on is that C-H-C during explains room of shielding. Hydrogen bonded with 2 carbons duh. But man I understood the concept. Thanks
thank you very much i didn't know a single thing about nmr spectroscopy..tried to understand it from the textbook but didn't get a single thing now its clear.. thank you..very much
thank you so very much sir. you have alwz been my messiah right before the exams. but this was the best becuz you are the first person who could actually make me understand NMR very very clearly. thank you again :)
I have studied shielded protons need a stronger applied field to produce the absorption signal.. u r telling that shielded protons require less energy... pls clear my doubt let me know where wrong iam going..?
It depends on the type of machine.If you are keeping magnetic field strength constant, shielded proton requires only less amount of energy (remember magnetic field is constant here).We are mostly using this type of machines.Other type is just vice versa....But we don't build machines that has both field and energy as dynamic variable.
You are right!! that's why they are called shielded protons because you need more energy to degrade their charge cloud!! Chodu's Biology is wrong here as he is in most videos...
But here we need to note that the shielded protons need less energy because their magnetic power gets covered with electrons and hence the energy applied to spin it to the opposite direction (repulsive forces between same poles) would be obviously less.
You make every complex lesson look simple. Your lecturing skills are excellent. Everything is well understood. Please keep it up you are helping a lot.
In NMR mechine why they stay same mode like north to north and south to south... Because u say at the first time north mode another atom north mode can not stay same side.. Because it intracts with each other..... At last i say ur lecture is very goood... I understand this lecture very gokd except this point..... Have any lecture about esr
Actually poles of earth is a opposite to magnetic poles, we take pole at which north pole of magnetic needle points as a north pole, but about the above video there should be direction of external magnetic field should from north to south pole...because outside the magnet magnetic field is from north to south pole.
Thank you sir for explaining the concepts in the simplest of ways. This helped me do well in my interview. Thank you so much. You are doing a great job!!
I'm confused by your example chlorine containing compounds. They are both ClCH2, which would be an unstable ion (the carbon has only 3 bonds), and in both of them the arrangement is the same (Cl-CH2)... whats going on with those?
The hydrogen atom is shielded due to more electrons from other atoms around it and hence the magnetic power is automatically reduced due to the shielding. If the magnetic power is less around the hydrogen, then less energy is enough to do the beta spin.
when the hydrogen is schielded ,the effect of the magnetic field will be reduced and for example instead of turning the hydrogen in 180 degres u'll just need to turn it in 60 degres to reach the resonance position and thus u'll need less energy
Rupambika Das because electrostatic interaction are quite high, so because of the interference which is already there, spin requires less energy to rotate that proton. Thank me later.
Dear Suman Bhattacharjee what do you mean by ClCHH or HClCH..... C-H-C is this is correct... are you sure about direction of magnetic field ..and conditions of resonance... The way of delivering lecture may be may be somewhat good,,, but this lecture is bunch of blunders...
Hello sir.....!! all ur lectures are way too easy to understand....u deliver d complicated concept into much much simpler way to b understood.....😃😃😃 u saved me in my degree exams and ur doing so in my msc exams.....THANK U SOO MUCH .....
shomu, i dont know how to express my gratitude toward ur lecture most especially mass spec. Honestly am so inspired from knowledge, the way u break it down. am happy God bless u

How can a hydrogen get attached to more than one carbon
Since hydrogen has a valancy of 1
also Cl-CH2 is the same as H-CCl-H
He didn't say that H is attached to more than 1 C atom....he was just trying to differentiate shielding on the basis of electronegativity of C and Cl

how a single hydrogen can be bonded with two carbons???????
