🧲❗️HH coupling constants in five-membered heteroaromatic rings, in particular ³J of the protons in the 2- and 3-positions, allow the heteroatoms to be identified (the more electronegative the heteroatom, the smaller is the value of ³J)

This spectrum is from 2 uL of sample in a 125 MHz benchtop spectrometer. Want to learn how it works? Come to the Instrumentation I session, Monday 4-5:45 pm in the Chapel bldg at #ENC2024 ENC - Experimental Nuclear Magnetic Resonance Conf #NMRchat

Some time ago, Sander (@sandersays.bsky.social) designed a #NMR children's toy (tower of Hanoi-like).
Now, we have a magnetic version as well.

Hi #NMRchat , does anybody know if the 'ball-seal' VT connection is a Bruker-specific part? We would like to obtain an extra one, the mating part to this probe, with a hosebarb connection. Are they commercially available?
