The dipole moments of eight α,β-unsaturated aromatic and heterocyclic aldehydes and ketones in dioxane solution were measured. The moments of the syn and anti conformations were calculated by vector-additivity schemes. The effect of the conformation on the moment of the C=O group was taken into account. The charge distribution was calculated by the Pariser-Parr-Pople method in order to estimate the polarization of the C=C bond.
