this is hands down the best chemistry channel i have every encountered. you're incredible, keep doing what your doing. the understanding i gain from your videos makes me enjoy my work so much more, im gonna recommend to all my teachers
I know im randomly asking but does anyone know of a tool to get back into an Instagram account? I somehow lost my password. I would love any help you can offer me!
You provide the most simple, yet very informative and direct IR spectroscopy video. I wished i watched this sooner. It really helped me understand its usage for my final year project. GBU sir!!
nice video. however, there´s one rule to consider about the absorption of light: 1- the IR only shows absorption when there is change in the dipole moment of molecule; and 2: Photon energy must equal the difference between energy levels. Classically the harmonic oscillator can have any energy. Quantum mechanically it only has discrete equally spaced energy levels given by Ev = (v + 1/2) hf. v = 0,1,2,... Selection rule: Absorption of light only occurs for ∆v = ± 1This means that each transition has the same energy change.
I am reluctant to write comments but oh my God this is an awesome explanation of something which I was not able to comprehend for ages given that I have never learnt Chemistry.
Excellent! Your approach of delivering concept is 5of 5 stars- simple language, good visual effects and and animations. Hats off to maker/ producers. I watched about 8 videos so far(stumbled on the videos lately) and they all impressed me. Keep going and looking forward to seeing more video lessons.
ive watched about 20 videos on this topic and i finally understand it thanks to yout video!! you explained this in such a smple way, everything makes sense now. THANK YOU
If you use ATR-FTIR that means that you won't have transmittance in y axis but absorbance and then you would have the opposite graph? this is how you basically get the spectra from ATR? I would appreciate if you could answer:)
A quick question, why the molecule absorbs the light matching the frequency of wagging/bending? So far I was thinking it absorbs only if the energy of the source light (of course having a specific frequency) matches the difference between energy levels of a certain atom in the molecule. Which way of thinking make sense?
sir...why will not molecule absord light at 1 hz or 3 hz.... by absorbing .. it could have vibrated 1 time or 3 time per second... why it chose to absorb 2 hz and 4 hz only ?
wavenumber=1/lambda (spatial frequency) is nothing but [frequency(C/lambda) / C(speed of light)].....yielding 1/LAMBDA they used this because frequency is always been a large number say in the form of 10^14 like that. so to make it look like a convenient they divided it by the constant C and named it spatial frequency....
what about the absorbing light under in thermal camere(IR) ? I mean, ı m trying to apply different paints on the automobile ındustry.Paint musnt be seen by thermal camera.Which functional groups can be advised by you ? I m touching epoxy,acrylic or vinly sistems ? thank you..
You say all carbons are the same and thus vibrate the same, but what about isotopes of an atom? Does a carbon 13 have a different IR reading than a carbon 14?
I have a question. In regards to the colour of the object being examined. Is it feasible for the colour to be determined via the fingerprint of the substance?
No words to describe this lecture. But what a pity...? This fantastic video has been copied by a copy cat "Shomu's Biology" and he comes number 1 in search results.
Jesus loves you ❤️ Please repent and turn to him and receive Salvation before it is too late. The end times written about in the Bible are already happening in the world. Jesus is the son of God and he died for our sins on the cross and God raised him from the dead on the third day. Jesus is waiting for you with open arms but time is running out. Please repent and turn to him before it is too late. Accept Jesus into your heart and invite him to be Lord and saviour of your life and confess and believe that Jesus is Lord, that he died for your sins on the cross and that God raised him from the dead. Confess that you are a sinner in need of God's Grace and ask God to forgive you for all your sins through Jesus. Jesus loves you. Nothing can compare to how he loves you. When he hung on that cross, he thought of you. As they tore open his back, he thought of your prayer time with him. As the thorns dug into his head, he thought of you spending time in the word of God. As the spears went into his side, he imagined embracing you in heaven. Jesus longs to be with you. Please repent and turn to him and receive Salvation before it is too late.
@FMA B thanx alot, i will look for that As i understand from u , for each wave length there is different energy levels? So wave numbers distinguish between them? What i know so far is that each lambda is associated with one energy level.
Astonishing! Crystal clear, beautifully illustrated and presented.
This is the best video on IR spectroscopy I have come across.
Amazing video whole 15 minutes is investment.

Excellent , awesome , cannot be any better . Thank you
Wow! That's saying a lot. Thank you!
@@Knowbee your video is the best.i feel excited .
This saved me a hell of a lot of time and hair-pulling working out how NIRS can check BOLD response data.Thank you.

OMG just finished watching New Girl and I have the weird feeling that the actor playing Schmidt is the same person who did the voice off of this video

Very easy to understand especially when you know nothing. Thank you for explaining everything you talking about. Very good for beginners.
Plzz don't remove ur vdos till the last day of planet exist
Frrrrr
Awesomeeeee! Keep going sir. You are the best
This is one of the *BEST* videos on the subject. Thank you!

From where are you bro which college
@@riteshrk18 Vanguard University of Southern California.
@@matthewkenslow722 are you on instagram bro i m from india yaar....plz give if you are available...we will have some doubt discussion
@@riteshrk18 Hi, Yes, I'm on Instagram as my name. What would the discussion be about?
best organic chemistry teacher i have ever get
Thanks for upload this video!
Sr.what is the software that do you use to edit your graphs and perform the animations?
you are a wonderful scientific teacher, who are you? I like to talk to you. I am improving teaching styles.
Hello Sara! Just send me an email through my channel and I'll be happy to talk to you.
@@Knowbee sarashourni@gmail.com
Thank you for your attention.
After all these years in chem/Ochem labs and I FINALLY understand this stuff
Why did you not just use the actual frequency at which the carbonyl absorbs IR in the example?
Excellent, I´m studyng about green house efect and this give clearness about the vibration modes and the spectrography
Best viduo ever, i watch the viduo every time i need to remember the info., thank u so much
Never understood the concept until now! Thank you so much!

Interesting that half of the lower frequency wouldn't make it vibrate. Not enough energy apparently; it can't vibrate slower.
wavenumber=1/lambda (spatial frequency) is nothing but [frequency(C/lambda) / C(speed of light)].....yielding 1/LAMBDA they used this because frequency is always been a large number say in the form of 10^14 like that. so to make it look like a convenient they divided it by the constant C and named it spatial frequency....
Wrong graph.....it will not start with 0,0.... start with 100% 9:10
THANKS SOOOO MUCH. ACTUALLY IT IS SOOOO SSSOOOOO CLEAR.
Sir.. why frequency is not put on x axis but wavenumber?
Great Explanation !
Just one question :
Why in the plot of amount of light transmitted vs wavenumber, the wavenumber decreases from left to right ?
what about the absorbing light under in thermal camere(IR) ? I mean, ı m trying to apply different paints on the automobile ındustry.Paint musnt be seen by thermal camera.Which functional groups can be advised by you ? I m touching epoxy,acrylic or vinly sistems ? thank you..
so easy !! thank you for the amazing explanation !
You say all carbons are the same and thus vibrate the same, but what about isotopes of an atom? Does a carbon 13 have a different IR reading than a carbon 14?
Amazing explanation, subscribed
Really great video but I'm not sure why you use the pronoun "he" to describe a detector? A detector is an "it" is it not? :)
For the molecule too apparently 3:13. Maybe molecules come in male and female? Wow, as do detectors. Now there's a PhD study.
I have a question. In regards to the colour of the object being examined. Is it feasible for the colour to be determined via the fingerprint of the substance?
thank you so much !!! it's very helpful!
I thought I never gonna understand IR, Thank you so much you taught what professors fails to do.
Nice explain you thanks
Wow...I really understand this concept....thanx so much!
2:16 frequency
3:35 what exactly happens in spectrometer (hypothetical example)
4:40 graph
This makes my brain happy, lol
thank you!
Thanks for this! Every other video acts like we all should already know this stuff.
Good vdo for IR spectroscopy....it's really awesome...I can't go with any other vdos....keep going to put more vdo
great job man!!!
this is the best introductory video available on the topic!
Very informative and easy to understand.
wouh.. you are great, very well exampled for even a non science person can understand
why wavenumber vaies from 4000 to 0 ? or why it shows in decresing order ?
A video made spectroscopy interesting for me
Awesome..
Awesone explanation, easy to understand, congratulations helps me a lot.
Simple and informative show,
Thanks
Excelent
outstanding , Thank you

This was a very great presentation of I.R.--22 min video !!!
Many difficulties solve by this video...
your explanation is wonderful!
Thank u so much for the video!!!!
great job sir
Mass, bacan and very cool
Wow, thank you sir
Big thanks for you
thank you so
but why the wave number is used instead of frequency?
@FMA B thanx alot, i will look for that
As i understand from u , for each wave length there is different energy levels? So wave numbers distinguish between them?
What i know so far is that each lambda is associated with one energy level.
@FMA B much appreciated!
AMAZING, THANK YOU!!!!!
informative
