Polarized spectra were measured at 298 K. Temperature dependent spectra were measured using unpolarized light down to 20 K. The spectra at 20 K are well resolved revealing the features of spin-forbidden transitions and vibrational fine structure on some of the bands. Some of the spectra are deconvoluted to separate out the overlapping bands. The assignments are made usingD 3 symmetry for Ni(en)3Cl2.2H2O complex whileD 4 symmetry is used for Ni(OAc)2.4H2O. The energies of the spectroscopic states are calculated and compared with the observed transition energies. The distortion parameters are determined. the Indian Academy of Sciences, 1992 Electronic spectrum nationallicence high spin nationallicence nickel ion nationallicence distorted octahedral symmetry nationallicence 33.10 nationallicence 33.20 nationallicence 33.70 nationallicence Chandramouli GVR Department of Chemistry, Indian Institute of Technology, 600 036, Madras, India aut Manoharan P.
