Assignment of proton NMR spectra and conformational analysis by two‐dimensional heteronuclear relayed correlation NMR spectroscopy

Abstract

AbstractThe method of two‐dimensional heteronuclear relayed correlation spectroscopy was used to establish the assignment of the severely overcrowded part of the proton spectrum of menthol by relating it to the previously assigned carbon spectrum. Extrapolation of the signal‐to‐noise ratio obtained with overnight data accumulation on a 10 mM solution suggests that this experiment should be feasible on as little as 10 mg of a moderate‐sized organic compound.
