The 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 ove

Abstract
The complete assignment of the proton and carbon chemical shifts of 6‐O‐acetyl‐2,3,4‐tri‐O‐(3__S__‐methylpentanoyl)‐α‐D‐glucopyranosyl‐β‐D‐fructofuranoside, a naturally occurring flavor precursor of tobacco, is presented. These assignments were made by comparison of the spectra obtained from ^1^H‐detected heteronuclear multiple quantum coherence and ^1^H‐detected heteronuclear multiple‐bond connectivity two‐dimensional NMR experiments.
