| Abstract: | The electrical and optical properties (dipole moment, electrooptical and optical Kerr constants, molecular polarizability anisotropy, polarizability tensor, molecular refraction) of N,N-dimethylnitramine as the simplest N-NO2 derivative were studied by a set of experimental and theoretical methods with the aim to determine the components of the polarizability ellipsoid of the N-NO2 group and develop a valence-optical scheme for calculating the optical and electrooptical parameters of N-NO2 compounds. Conjugation of the p electrons of the imide nitrogen atom with the  electrons of the nitro group results in deviation of the properties of N,N-dimethylnitramine from the additive values. Comparative evaluation of the parameters of the Csp3-NO2, Csp2-NO2, and N-NO2 groups was made. |
