What's Nuclear Magnetic Resonance (NMR)? How Does It Work? What's It Used For? A Brief Introduction.

- What is Nuclear Magnetic Resonance (NMR) spectroscopy?
The NMR spectroscopy is an information-rich, non-destructive analytical technique that provides detailed information about molecular structure, dynamic processes and allows the direct observation of chemical reactions.
- How does it work? NMR spectroscopy uses the inherent magnetic properties of specific atomic nuclei to reveal the structure, identity, concentration, and behaviour of molecules in solid or liquid samples.
NMR relies on a property of certain atomic nuclei that causes them to absorb, then re-release, electromagnetic energy at characteristic frequencies. Shifts in the usual response frequency for a given isotope provide information about their immediate environment, including influences from nearby electrons and magnetic nuclei, making it possible to infer molecular identity, geometry, and more.
- Where is NMR used and for what reasons? Applications of NMR spectrometry span R&D and quality control for the chemical, environmental, petrochemical, pharmaceutical, and food and beverage industries. NMR fills essential research and clinical needs in biomedicine, proteomics, metabolomics, and more. NMR spectrometers range from cost-conscious benchtop systems to sophisticated research spectrometers with high-field magnets to maximize sensitivity and resolution.

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.

Thank you!

[@brunolisenko8488]

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.

Well explained and visualized. I didn't even imagine how the precession movement is. Thank you.

[@firstname3925]

I didn't even know what precession movement was

[@palavesaaravind1528]

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 🙌🏼

[@Gigimoskwitoz]

very well explaination and visualized . Thank You

[@joeljustin]

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.

[@raja-hl7gx]

good explaining

Super understandable video! Nice

[@niccolo99]

Fantastic, thanks for your help

Amazing! Thank you

[@amulyachandana8648]

Good explanation 🙏🥰 tq so much❤️

[@rohanjagdale97]

Thanks for the video .. :)

[@you11193]

thank you very much

[@ghadaslman5645]

This is so satisfying 💖👍👍

[@ahmadmunibhanifi3546]

Wow what a great video 🤩

[@neaumusic]

awesome

[@ahmetozdemir7173]

Thanks for video. If no pulse is applied, won't the protons rotating in the magnetic field emit any frequency?

[@janrdanprasad2914]

Please make more videos on NMR like this Thank you

[@chiaraodorici]

Thank you so much!! After my professor lesson, I didn't understand THIS much! You saved an exam :)

[@debbieko50424]

this is way better than my professor

[@thandolwethumaphumo6441]

great video. thank you

[@crownether9537]

Oh yea there you go!!

[@normafranceniasantossanche3078]

So nice video! Thank you.

Outstanding........❤❤❤❤❤

[@christianlopez-ramirez2350]

Does nmr require physical contact with material surface?

[@yabyab5861]

THANKS! It is too much interesting.

[@themultitaskerdoctorate5291]

best NMR video

[@denbalogh]

On the last graph, at 3:18, shouldn't CH2 have 3 peaks and CH3 4 peaks?

[@orhangokalpbuyukuysal]

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.

[@OS_Erol]

Shouldn’t the CH3 be a triplett instead because of the two Hydrogen atoms on the neighbouring carbon?

[@reliktoretto]

yeah i think so too

[@reliktoretto]

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

[@TheOGJeff]

Ken wheeler (theoria apophasis) is someone to check out on understanding some of this. Videos on Tesla, C. P. Steinmetz, magnets, electricity, photography, atoms

[@dongiovanni4331]

Ken Wheeler is a fraud, milking his followers all the way to the bank with pure word salad.

[@tobogansky]

That's cool, but will it blend?

[@TheReck12]

how did anyone come up with thisss
