Absorption Band and Wavenumbers in Infrared Spectroscopy 

in grad school where you're expected to learn pretty much everything yourself regardless of how good of a professor you have...this video has put together so many major concepts for IR in a concise and effective manner. thank you for this video. please continue making a difference for students like me.

The best content I found for this topic.

THANKS FOR SAVING MY LIFE SIR YOU ARE SAVING STUDENTS 1 VIDEO AT A TIME EVEN 9 YEARS AFTER U UPLODADED THIS VIDEO

The best channel I have found on chemistry

Amazing Stuff. It would be really helpful if you had a similar video for XRD as well!

Very clear and helpful, thanks a lot

It is a great lecture ! Thank you.

Yep, I'm going to keep watching until I get bored....so far, it's awesome

this tutorial is awesome ! thank you !!!

Perfect. Thank you.

these are really good videos.

These videos are a great summary of the basic principles of this analysis technique and have helped massively with my understanding of the topic. However, I'm explaining how this technique is used in a piece of university work and so am in need of academic references on the subject. I don't suppose anyone could suggest any of the original publications which describes this technique in detail? Thank you in advance and thanks again for the videos!

Love your videos

Great explanation

It is obvious the 'bond' does not absorb the photon, but the electrons in them, and electrons absorb photons according to their orbital state(s). Could you go into exactly why the stretching/wagging freq matches the photon absorption, eg: spectral lines, or do they? They seem like different things that may affect each other, but are distinct.

Nice one

Very useful video

wonderful

Great!

I like ur every vedio bro Pleaseeeeeee add more contents like this and please add more information in every vedio because u make it understand properly with examples and diagrams

sir please explain how can we know particular i.r frequencies of a molecule in i.r spectroscopic problems

Good

Applause 👏

13:09 More single bond character = higher wavenumber due to C-O on the molecule on the right

Is the answer going to be the same if the question wasn't specific like due to carbonyl group in the first question?

In sample problem 2 why are we not considering the masses of O and N?

5:52 Hehehe... He wrote heaver :P I'm only teasing. I enjoyed the video tons. Very helpful.

electron withdrawing and donating group point is not discussed in the video.

You mentioned lighter tha mass of atoms greater is the wavenumber but C=O has 1700-1800 but C=C has 1680-1600 why so? C has less mass than O so shouldn't C=C have higher wavenumber than C=O

'we're just gonna accept this equation as true' haha.

probably a good video but i stopped at 50 seconds when i heard you say aa-ffect 😭
