Abstract
The electric dipole moments of diphenyl sulfide, sulfoxide, and sulfone and their derivatives were determined in benzene solutions at 25°C. The observed moments are used to estimate the mesomeric moments on the assumption of the vector addition of group moments. The mesomeric moments of the phenylmercapto, phenylsulfinyl, and phenylsulfonyl groups are estimated to be −0.12, 0.10, and 0.44 D, respectively. The steric effect of ortho-substituents is also discussed on the basis of the dipole moment data.Keywords
