Abstract
The dipole moments of diaryl carbonates I-V in benzene solution are consistent with the Z,Z-conformation (A) in which the conformation of simple esters is repeated in the two moieties. The E,Z-form (B) was not detected; it may be either present as a quite small fraction or only with specific, overcrowded structures.
