Spin Spin Splittting is my new favourite scientific term :)

[@Obama_OReilly]

Super neat. Dramatic cinematography as well around 5:30 - makes the robotic arm way scarier

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

YOU SAVED MY LIFE! Thank you a lot for this and all the other nice videos!

[@lynnb7681]

I haven't looked at chemistry in over 20 years since getting a degree and was astonished by how small these instruments have become!

[@salena258]

Thank you! This was wonderful!!! I didn't remember all of those pieces from my O-chem classes.

[@esmeraldaelhamzawy9114]

An amazing video, and very illustrative. Thank you.

[@flyinghakusai]

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

[@xXUniqueSunRaysXx]

This video is awesome, it gave me a comprehensive idea about nuclear magnetic resonance. Thanks

[@vishalikalyanakrishnan9872]

wonderful vedio. provided a great deal of information. please keep uploading such useful vedios :)

[@ubiquim]

These clips are superb.

[@fiyyazhar7971]

thank you a lot! this video is helping me so much

[@AMJ2202]

Cool cette vidéo, j'ai beaucoup appris merci beaucoup et bonne continuation. C'est grâce a des gens comme vous que la science est universelle. Maëlys

[@gautambhall]

Thanks for video.. keep supporting science student by such practical work..

[@interplanetaryastrophysici7979]

Dies ist ein sehr gutes Video. Ich habe viel gelernt. Danke!

[@yuvaasampath3491]

i love brucker, nice presentation,easy understanding, interesting to me

[@DreamerJH87]

wow, it's really useful stuff.
Thanks so much for it !

[@Staunte]

Fourier Transformation is also used in X-Ray crystallography amongst other things related to chemistry.

[@yes4me]

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

[@yuwan7417]

Thanks, it is very useful.

[@ShBSultan]

A great video.

[@macmenmen]

Thanks so much for posting :)

[@pratik968]

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

[@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

[@davidneff6347]

nice job

[@Vrig]

It might be just me, but doesnt the nmr magnetic field pertrude from the cylinder metal casing in a downwards direction? If so, shouldnt his work station be more than 2m away from the NMR for satefy reasons?

[@juschet8]

very good video.

[@jialuyu5505]

good video !

[@prabhulalsuwalka1407]

thanks for this video

[@mptmatthew]

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.

[@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

[@TrilloSquillo]

The chemical shift for OH and amino hydrogens can be from o.5 to about 5.0 ppm (from "free" OH to a lor of H bonds)..and those that appear downfield, at about 10-12 ppm are carboxylic acid OH hydrogens (which have reduced electron density due to H bonding and are thus even more deshielded)

[@Fioooo32]

Great video .. !
Clear and intresting..

[@ksvsuperchannel7083]

i have a doubt ...that is the OH is the least one and it is least shielding so it come under deshielding ...but u have presented it in shielding area

[@plenarak]

Thanks so much

[@hardik9005]

nice ty sir ...............

[@TheIntrepidWolf]

Good video. A bit more information on analysis of the peaks would help and some help on working out how to tell how many adjacent protons are near each group. This topic is one of the hardest in A2 chemistry I found, not because it's that difficult, it's that the rules are rather vague.

[@AtomicCactus]

I love Bruker :-).

[@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!

[@romaahmetov5550]

super

[@a1b2c3z44]

So could you precisely identify organic substance of such complexity as lets say tramadol?

[@mariasani2495]

Pino K. K. with NMR and MS for sure!

[@junior1984able]

shoudnt he be wearing gloves when handling the hydomethene

[@hayetbenaicha231]

شكرا ممتاز

[@hayetbenaicha231]

شكرا لك على شرحك الوافي

[@iBubzi]

Les TS2 aimez !

[@metro2089]

I though only us electrical engineers used fourier

[@mohammedelshaer6884]

THERE IS MISTAKE IN ORIENTATION OF MAGNET IN THE FIRST

[@MackNJacishopper]

Exactly what i thought. I think they got it wrong.

[@ALHIMlK]

No gloves, no safety glasses, no labcoat, chloroform... The video was made when safety regulations were lax. good ol' days, haha
