Good topic, I just had a related thought: can I use the term in my NMR
course to say it's the only spectroscopy that gives atomic resolution
- meaning, here, that every NMR-active atom is distinguishable from
its neighbours thanks to its unique chemical shift. At good enough
resolution, i.e. field strength... Is it fair to use the term here or
would you object since I am not talking about spacial resolution but
something that could maybe be called 'chemical' resolution? But it is
still 'atomic', isn't it?
Cheers, Bärbel
