2D NMR Analysis (COSY/HMQC) - Assigning Peaks Using COSY/HMQC (Part 1 of 2)

[@micabad]

I have a really bad professor for the Graduate Level NMR class. I just bombed my last exam over 2nd order & conformation analysis. We are currently going over 2D-NMR and these videos are very helpful. Thank you.

[@user-nf4uq4zz7u]

me too..

[@vhaalgorn]

wait a minute, you were doing 2D NMR at graduate level? and here I am, doing this in my first undergraduate year, just hanging between the edge of life and death, wtf is this.

[@funbaby5038]

Hey can you please help me i have my final exams in next week.
I'll have to assign values so can you please help me in understanding

[@kajaltara4313]

Your videos have helped me so much. I was struggling for ages as I have never really grasped NMR in general and as soon as I watched your channel it just seemed to click. Thank you so much for your videos, I really appreciate it! :)

[@antonsund7170]

Thanks very much! Your video just helped me out a ton! My professor just explained it really bad, and I have to know exactly this 2D stuff for my exam. Great work.

[@TonyStJohn]

Great! I'm glad to hear it was helpful for you!

[@robby7997]

Thank you! lectures are very hard to follow with everything being online and they never realy explained how to read COSY/HMQC. This made it very clear

[@dr.srinivascsir-jrfgatessr3729]

It is a good example, that helped to understand the concept a lot. Thank you so much for this great stuff.

[@romulojesus4653]

Your videos are being very helpful! Thank you very much!

[@deekshajoshi8511]

You explain wonderful

[@leehooixian4213]

It is really very helpful and thanks for your effort in explaining this!!

Thanks for the video! Hello from Brasil

[@DarkAng3l1106]

Very well explained, thank you very much!

[@psrivastava6993]

Very nice explanation

[@Ayatessabi]

Incredible, you explained it perfectly! thanks a lot!

[@TonyStJohn]

You are very welcome! Thanks for the nice comment!

[@deekshajoshi8511]

Sir please explain the cosy spectrum of ethylbenzene and acetaldehyde

[@EcExplorer]

At first, I thought the table for benzene H determination is a silly thing. But really it helps a lot for beginners :D

[@phuongtuphamle4625]

Hi Thank you very much it is very useful!

[@simedinson984]

feels bad man when you have this as a base course in organic chemstry

[@koteppas7287]

nice Hint's....., I need to know more on 2d interpretation

[@Zeynaxy]

Thanks!!

[@taejinkook4290]

Is it ok to have a coupled that 4 bonds away, in the COSY? I'm doing an elucidation and from COSY analysis I saw a coupled between a proton-proton that 4 bonds away: 1st scenario is a meta coupling and one of the meta proton was coupled to the methylene protons that 4 bonds away,
And the 2nd scenario is between a symmetrical aromatic proton to and to an olefinic carbon attached to the aromatic carbon.

thanks a lot ............

[@victorsinghayam297]

everything is clear except from the COSY, how the carbon the peak position in 125 126 help to assume as Carbon number (9, & 10), for aldehyde or Carbon number 1 to assume to the Carbon peak at 190, is ok from the aldehyde peak position in the chemical shift of C-NMR. How, peak at 117 is assumed as carbon 7?

[@dawsansanhtay3935]

thanks

[@elilevit4574]

Looking at my HSQC, I see one carbon signal which correlates to two different H signals. How can I tell which Hydrogen is on the carbon?

[@augustammuoegbulam2145]

How do I send an NMR data for analysis?

[@satishkumarch3447]

Hai sir, i am satish kumar i have one doubt why NH2 protons is came one is aromatic one is aliphatic region

[@tt7762]

What's the difference between HMQC & HMBC??
Is the HMQC same as HSBC??

[@PritomAhad]

When you say they r correlating (in cosy spectrum) wdym exactly

[@monkedonkey8095]

The protons couple (have a J value)

[@stardustdragon1498]

Do you have any videos on HSQC interpretation?

[@zerminaaziz2924]

What is Name of this chemical structure?

[@avtaras]

I am in Grade 10 and I find this incredibly interesting & useful :D

[@abdallahbekheet774]

is there a reference on the topic?

[@aaashish4488]

Make a video about HSQC

[@yognathacharya3112]

name of this compound..plz
