Proton Nuclear Magnetic Resonance (NMR)

[azzuri98]

This kind of video is so practical!! Thank you for uploading.

[shbsul]

A great video.

shoudnt he be wearing gloves when handling the hydomethene

Spin Spin Splittting is my new favourite scientific term :)

[juschet8]

very good video.

[ubiquim]

These clips are superb.

Thank you for your comments regarding the OH / CH2 peaks. The chemical shift of OH is very dependent on solvent and other experimental conditions so cannot be assigned by chemical shift alone.

[reaperwalter15]

I think they have shown the peak for CH2 at 2.5 instead of showin at 1.6 and opposite for OH.

Atleast the videos from RSC should be atleast reviewed onced before posting!

[deeekaaa21]

Good video.. 

[alexnkassiesavage]

Very awesome video, I just had a lecture on these exact subjects and this shed some serious light on what it all looks like in the laboratory setting. It kind of sucks to learn about how to read the charts and what everything means without even having a clue what the NMR machine looks like. Thank you!

[1986liberty21]

I did this work for my exam of chemical analist on MLO. I want to know where can I do the studie to become NMR specialist? plz replie

[glianx]

i hope my school can afford to purchase 1 unit of nmr. its very effective for structural elucidation...

[kingfinnc]

i don't know if i'm wrong, but i think i'm not:

but the chemical shift of the shown H in the OH-group has to be higher than the ones of the CH2-Group ?!? must be at 5,5ppm or somewhere near that.

[free0fight]

@kingfinnc yup, youre right...I was watching some other videos on this same subject and they showed that the OH chemical shift was in the 4-5 ppm range...idk what is up with this one in this vid...lol

[pratik968]

@kingfinnc no -ch2 gp is linked to electronegative atom so the value is higher than OH

[newaaliyah]

H1 NMR of ethanol:

I noted that in this video, the OH shift appears at around 1.6 ppm... However, shouldn't the OH proton be more downfield since it experiences more deshielding due to oxygen? The splitting is accurate because OH hydrogens are usually singlets... The CH2 protons do not experience as much of an inductive effect as the H bonded with the oxygen.

The H chemical shift of OH should appear near 5.3 ppm

That's a bruker biospin/bioshield 300 Mhz, the higher the frequency the higher the magnetic field and trivially speaking the machine gets bigger. At the 800 respec. 1100 Mhz unit at our institute you really need stairs to get the sample in to the probe. To measure other nuclei you just need a "special" probehead (not really explained in this video) but basically you're right, any "magnetic" nuclei can be measured with any NMR machine

[Subspace4d]

Thank your for upload! Do you know abought Nuclear spin tomografy? Also did you knew that you do not need nitrogen jacket if you have some special thermo foil wound around the helium jacket?

[JanAap04]

Wow this is really amazing. This video clarified a lot, thanks. Any idea how "old" this NMR machine is? From what I know, previously these machines required stairs to reach the top of the machine. Or is this version much smaller as this machine only does proton NMR?

Cheers

I think this one can detect other isotopes, but the massive ones work with smaller samples, so for like forensics you might use a big one because you only have a small sample, and therefore need a bigger magnet. i think this is why.

[nehajohar]

its really helpful...

thanks a lot:)

[Kilozro]

very nice

thanks

[maglight117]

what about slicon-29?

[MarcusDiMarco7]

Good video, but not exactly what I was looking for. I was looking more for a video that focused more on interpreting graphs and being able to draw molecules from that. But I very much enjoyed the background to how the experiment is done, thanks.

[AtomicCactus]

I love Bruker :-).

[DreamerJH87]

wow, it's really useful stuff.

Thanks so much for it !

[irizarxyz]

This is brilliant!!! It was so well explained!!

But I'm still a bit confused about the peak splitting and n+1 rule!! Can someone explain please? (Textbooks make it more complicated)

[noinlair]

trichloroMEE-thane

Lol. I've never heard it pronounced that way and I've had a TA how pronounced carbocation like carbo-cation.

[07TonzPau]

lol ive got a mid sem on this innnn 10 hours time

[flyinghakusai]

WOw, I really wish I found this video sooner! Thank you so much!

[yh458]

very helpful!

[plenarak]

Thanks so much

[yes4me]

This is great. I can't lack the word to express my thx 5/5

[fh1mahfanzai]

this is so cool, finally put my lecture into an experiment

[Leviathan42]

well done

[farhmoha]

nice

[macmenmen]

Thanks so much for posting :)

[myusername20202020]

Thanks for sharing, this is perhaps the best video I've seen about basics of NMR; it is very well and concise explained.
