Algorithm for the calculation of the dipole moments of bonds in polyatomic compounds

Journal of Structural Chemistry, 1986
The question of the physical meaning of the so-called dipole moments of bonds was considered in reports [i, 2]. This concept, as we know, &s widely utilized in chemistry in the analysis of intermolecular interactions and in the study of the optical properties of polyatomic molecules.

Dative bond to dipole moment

1995
This chapter focuses on the dative bond and the dipole moment. A dative or co-ordinate bond is a covalent bond which originates from the donation of an electron-pair from one atom (or group of atoms) to an empty orbital on a second atom. Although the origin of the electron-pair in a co-ordinate bond is usually a lone pair on the donating atom, it can ...

Dipole moments and conformation of Schiff bases with intramolecular hydrogen bonds

Journal of Molecular Structure, 2000
Abstract The dipole moments of series of Schiff bases, which are derivatives of salicylic aldehydes in CCl4 solution were measured. The influence of the substituents on the conformation of the molecules, the intramolecular hydrogen bond energy and tautomerism were studied by means of semi-empirical PM3, AM1 and ab initio methods.
