## Abstract The ^13^C chemical shifts for 1,3βdithiane and 9 methyl substituted derivatives are reported. Only three of the methylβ1,3βdithianes were conformationally anancomeric and hence the conformational equilibria must be taken into account when deriving the values of the different substituent
The 13C-NMR spectra of 48 cis alkenoic acids and esters (C8-C20), 18 trans alkenoic acids and esters (C9-C18), and 26 polyenoic acids and esters (C18-C22) are reported and interpreted. The characteristic features of such spectra which permit structural assignments to be made are discussed.
