    Abstract:
    The polarized electronic spectra of single crystals of bis(diethyl dithiophosphato)nickel(II) at ambient and cryogenic temperatures have been analyzed with respect to the polarizations and temperature dependence. Polarizations have been interpreted in terms of molecular orientations as seen from three orthogonal views of the monoclinic crystal. The temperature dependence of the band intensities has been used to estimate the energies of the allowing vibrational modes for the various bands. Fine structuee in the spectrum at 4.2°K reveals at least six allowing modes followed by extensive symmetric mode progressions in quanta of 300 cm-1. Assignments of the electronic energy levels are made in terms of the centrosym-metric space group Dm and are in agreement with theoretical predictions. © 1972, American Chemical Society.
