✦ Synopsis

Abstract

Carbon‐13 NMR spectra have been obtained and analyzed for a series of saturated linear and cyclic sulfur‐containing organic molecules. For the large cyclic polythiaethers whose proton spectra are broad and unresolved, it is found that carbon‐13 spectra are sharp and well resolved. The resonances of all carbons fall within the expected chemical shift ranges. Based upon the comparative resolution in the spectra of large and small cyclic species, it is concluded that whatever conformational motion may exist within the rings must be occurring very rapidly on the NMR time scale.
