Conformation of 1,3-dichloroacetone

Abstract

The molar Kerr constant (35 x 10^-12) and dipole moment (2.29 D) of 1,3-dichloroacetone in carbon tetrachloride are shown to be compatible with an equilibrium mixture of planar cis/non-planar gauche (6) and non-planar gauche/non-planar gauche (8) conformers with the latter predominating.
