Conclusions
-
1.
In systems with a nonsymmetrical arrangement of the unshared electron pairs (UEP) relative to the axis of symmetry, the dipole moments (DM) of the UEP must be taken into consideration, while in systems with a symmetrical arrangement of the UEP, the DM of the UEP enter into the DM of the bonds obtained according to an additive scheme.
-
2.
A quantum mechanical consideration of the DM of the C-O, C-S, and S-O bonds, as well as the UEM of the sulfur atom, was performed by the MO LCAO method.
-
3.
The most probable values of the DM of the bonds and UEP were calculated for an additive calculation of the DM of molecules of sulfides, sulfites, and sulfoxides.
