| Summary: | Dipole moments of cyclic esters of carbonic acid in benzene solution are measured and compared with theoretical calculations. Dipole moments are reported for ethylene carbonate (4-80D), 1:3 propylene carbonate (5-21D) and 1:3 butylene carbonate (5-23D). These values are shown to be consistent with theoretically calculated values for the corresponding open chain compounds dimethyl carbonate and diethyl carbonate in the appropriate stereochemical configurations.
