Molecular polarisability. The apparent conformations of acetic anhydride and diacetyl sulphide as solutes in benzene or carbon tetrachloride
Abstract
The apparent dipole moments and molar Kerr constants found for Ac2O and Ac2S as solutes in carbon tetrachloride or benzene are reconcilable with non-planar conformations derivable from the s-cis models by rotating each acetyl group within the range 130–140° in a clockwise sense (looking from the central atom towards Ac).
