at various temperatures. Stabilityconstants (K1 and K2) and stoichiometries of formed adducts (1:1 and 1:2 ligand to metal ion) were calculated by computer refinement of experimental spectral mole ratio data by SQUAD program. The results indicated that the donor number, dielectric constant, the acceptor number of the solvents play an important role in the complex stability. Besides, the shape and size
(FT-IR, FT-Raman, (1)H NMR, (13)C NMR) of 1-(4-chlorophenyl)-3-(4-nitrophenyl)triazene, CNT. The optimized geometry, harmonic vibrational frequencies, infrared intensities and Raman scattering activities were obtained at the B3LYP/6-311++G(d,p) level of theory and thermodynamic functions were calculated at the same level. A detailed interpretation of the Infrared, Raman and NMRspectra of the compound was
