For those who get confused because of the number of the signals: CH2 (methylene) have 3 different energy levels and influence on the neighbouring spins (CH3) = 3 signals CH3 (methyl) have 4 different energy levels and influence on the neighbouring spins (CH2) = 4 signals In conclusion; energy levels split the neighbour's signals.
It must be the brightest minds out there in Physics who discovered NMR phenomenon. And this principle was later picked by medical professionals in making the MRI machine.
Great explanation and visualization, thank you! I would just like to point out that your last figure has incorrect labeling of the NMR spectrum (on the right). The chemical shift with 3 peaks comes from CH2, not CH3; likewise, the 4-peaks chemical shift comes from CH3, not CH2. You explained correctly previously, just the labeling that was done backwards at the end.
CH2 (methylene) have 3 different energy levels and influence on the neighbouring spins (CH3) = 3 signals CH3 (methyl) have 4 different energy levels and influence on the neighbouring spins (CH2) = 4 signals In conclusion; energy levels split the neighbour's signals.
i was wrong. its explained right. because the neighbouring hydrogens are splitting the signal. so the 2 hydrogens on the cesond carbon atom can have 4 differrent spin configurations in which 2 have the same amount of energy. therefore u have signal splited into 3 peaks cuz those 3 spin configurations of the second carbon atom (ch2) influence the signal of the first carbon atom (ch3). 3:06

Thank you!
Great explanation. It actually helps me to understand NMR more easily.. Thank you so much.
Well explained and visualized. I didn't even imagine how the precession movement is. Thank you.
I didn't even know what precession movement was

very well explaination and visualized . Thank You
Great visualization and I didnt find the reason for spin spin coupling in any other video r books. But explained it like a piece of cake. Thank you 🙌🏼
this is way better than my professor
Thank you so much!! After my professor lesson, I didn't understand THIS much! You saved an exam :)
good explaining
Super understandable video! Nice
This is so satisfying 💖👍👍
Amazing! Thank you
1:17 Spotted the Tardigrade
Good explanation 🙏🥰 tq so much❤️

This is actually dope as fck. This type of shit fascinates me
Wow what a great video 🤩
On the last graph, at 3:18, shouldn't CH2 have 3 peaks and CH3 4 peaks?
CH2 (methylene) have 3 different energy levels and influence on the neighbouring spins (CH3) = 3 signals
CH3 (methyl) have 4 different energy levels and influence on the neighbouring spins (CH2) = 4 signals
In conclusion; energy levels split the neighbour's signals.
Fantastic, thanks for your help
Please make more videos on NMR like this
Thank you
Outstanding........❤❤❤❤❤
Shouldn’t the CH3 be a triplett instead because of the two Hydrogen atoms on the neighbouring carbon?
yeah i think so too
i was wrong. its explained right. because the neighbouring hydrogens are splitting the signal. so the 2 hydrogens on the cesond carbon atom can have 4 differrent spin configurations in which 2 have the same amount of energy. therefore u have signal splited into 3 peaks cuz those 3 spin configurations of the second carbon atom (ch2) influence the signal of the first carbon atom (ch3). 3:06

Well explained..❤️👍👍 Thank You 🙏
Thanks for the video .. :)
Thanks for video. If no pulse is applied, won't the protons rotating in the magnetic field emit any frequency?
Does nmr require physical contact with material surface?
thank you very much
great video. thank you
So nice video! Thank you.
best NMR video
THANKS! It is too much interesting.
Oh yea there you go!!
awesome

Ken Wheeler is a fraud, milking his followers all the way to the bank with pure word salad.
That's cool, but will it blend?
Accurate Wale attendance do😂😂
how did anyone come up with thisss
