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

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

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)

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

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.

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

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

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.

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?

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!
