A theoretical analysis of properties of the shared interactions between two neighbouringnitrogen atoms in a variety of compounds is presented, based on properties of charge distributionsderived from 6-31 ++G** wave functions. Bond is characterized in terms of its bond order, bond ellipticity and the quantity of Laplacianof p at the bond critical point. The difference between the bond path angle and the correspondinggeometrical angle provides a measure of the degree of relaxation for the charge density away from thegeometrical constraints imposed by the nuclear framework. Comparisons have been made betweenthe nitrogen-containing compounds and isoelectronic hydrocarbons. Values of the NN bond energies, based on the properties of NN bond interatomic surface, aredetermined in three schemes.
