Molecular structure and electric properties of N -methyl- N -nitroaniline and its derivatives
2001
A comparative study of the molecular structure of N-methyl-N-nitroaniline and its derivatives is carried out employing the Kerr effect and dipole moments methods in combination with the crystallographic analysis. The obtained experimental structural data agree with the quantum-chemical calculations by the B3LYP/6-31G p and MP2/3-21G p methods. The measurement and calculation results are used to draw conclusions about the mutual interaction and role of various substituents to the Nmethyl-N-nitroaniline molecule. q 2001 Elsevier Science B.V.

Studies on proton acceptor ability of SOx-containing compounds
1995
Abstract IR spectra, dipole moments and molar Kerr constants of complexes of phenols with compounds containing SO x groups were studied to establish the structure of the complexes and the parameters characterizing the proton acceptor capability of these compounds. ( μ H , Δ ( mK ), log K and δ 0 ). It has been suggested that the new parameter Δ ( mK ) — the structural additive difference of the molar Kerr constant — makes it possible to determine changes of polarity and polarizability of the systems during complex formation.
Studies on the proton acceptor ability of phosphoryl compounds
1996
Abstract Dipole moments and molar Kerr constants of complexes of phenols with phosphoryl compounds were studied to establish the structure of complexes and parameters characterizing the proton acceptor ability of these compounds. The structures of these complexes and parameters ( μ H , Δ ( mk ) S , log K and δ 0 ) were established. It has been suggested that a new parameter Δ ( mK ) S — structural additive difference of the molar Kerr constant — makes it possible to determine changes of polarity and polarizability of the systems during complex formation.
