摘要：

Di(4-ethylphenyl)carbazone and its Ni(H), Cu(H) and Pd(H) metal complexes have been synthesized and characterized by magnetic moment, IR, ESR and H-1 NMR spectral measurements. The solvent effect in a series of polar and non-polar solvents of varying dielectric constants and refractive indices are estimated by recording electronic spectra (Sl band) of the above compounds. These data are used to determine the magnitude and direction of the electric dipole moments in the first electronically excited states. The results indicate that the observed band systems in these compounds may be attributed to pi* <-- pi transition. (C) 2001 Elsevier Science B.V. All rights reserved.
