The 1H and 13C resonances of 3-aryl-2-oxazolidinones and 3-aryl-2-thiazolidinethiones have been examined.The conformational isomers of restricted rotation about the aryl C-N bond could not be detected for both of the nuclei.The additive shift parameters, measured for carbon chemical shifts, are found to be higher in the sulphur substituted hetero ring.
