Molecular polarisability. The dipole moments and molar Kerr constants of benzaldehyde, acetophenone, 1,4-diformylbenzene, and 1,4-diacetylbenzene

Abstract

Dipole moments and molar Kerr constants (×1012) at 25 °C are recorded for the following as solutes in carbon tetrachloride: benzaldehyde (2·98 D, +504), acetophenone (+330), and 1,4-diformylbenzene (2·25 D, +57·6). These results, together with published data for 1,4-diacetylbenzene, yield information on the preferred conformations of 1,4-diformyl- and 1,4-diacetyl-benzene.
