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

[@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!

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!

[@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

[@ubiquim]

These clips are superb.

[@vishalikalyanakrishnan9872]

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

[@gautambhall]

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

[@fiyyazhar7971]

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

[@interplanetaryastrophysici7979]

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

[@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

[@yuvaasampath3491]

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

[@DreamerJH87]

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

[@yes4me]

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

[@macmenmen]

Thanks so much for posting :)

[@yuwan7417]

Thanks, it is very useful.

[@ShBSultan]

A great video.

[@davidneff6347]

nice job

[@Fioooo32]

Great video .. !
Clear and intresting..

[@jialuyu5505]

good video !

[@prabhulalsuwalka1407]

thanks for this video

[@Staunte]

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

[@juschet8]

very good video.

[@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)

[@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

[@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.

[@plenarak]

Thanks so much

[@pratik968]

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

[@hardik9005]

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

[@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

[@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!

[@AtomicCactus]

I love Bruker :-).

[@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?

[@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

[@romaahmetov5550]

super

[@hayetbenaicha231]

شكرا ممتاز

[@hayetbenaicha231]

شكرا لك على شرحك الوافي

[@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!

[@metro2089]

I though only us electrical engineers used fourier

[@iBubzi]

Les TS2 aimez !

[@ALHIMlK]

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

[@junior1984able]

shoudnt he be wearing gloves when handling the hydomethene

[@mohammedelshaer6884]

THERE IS MISTAKE IN ORIENTATION OF MAGNET IN THE FIRST

[@MackNJacishopper]

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