Abstract

Energy barriers to rotation about Ar—O bonds have been obtained from an analysis of the variable temperature n.m.r. spectra of a number of highly substituted diphenyl ethers. These barriers are explained on the basis of structural and conformational effects and their implication for the resolution of optical isomers is discussed.
