Abstract
The deuterium NMR spectrum of perdeuterated cis-decalin in liquid-crystalline solvents is studied over the temperature range -5 to ∼160 o C. The spectrum exhibits dynamic features due to the interconversion process of the cis-decalin molecules. For the quantitative analysis of the spectra, complete peak assignment is performed (i) by using selectively deuterated cis-decalin in the β-position, (ii) by using 2D exchange spectroscopy at low temperatures,and (iii) by fitting the observed spectrum with that expected from the minimum energy structure derived from molecular mechanics calculations
