The Vibronic Spectrum of Bis(diethyl dithiophosphato)nickel(II). II. Temperature Dependence and Fine Structure Analysis1a, b


Journal Article

The temperature dependence of the electronic spectrum of bis(diethyl dithiophosphato)nickel(II), Ni(dtp)2, has been investigated, particularly in the temperature region below 80°K, and its band intensities have been found to conform well to the formula IT = Io coth (hv/2kT). Extensive vibronic fine structure on the first three d ← d bands at 70°K and below reveals at least six promoting modes followed by extensive symmetric mode progressions in quanta of 300±2 cm-1. The frequencies of the promoting (ungerade) modes have been compared to those of the ground state as revealed in the infrared and Raman spectra. The Raman spectrum shows clearly the totally symmetric stretching mode at 305 cm-1 corresponding to the excited-state mode responsible for the 300-cm-1 progressions in the vibronic spectrum. © 1973, American Chemical Society.
