✦ Synopsis

The resonance Raman spectrum of [ Pt (en) 2] [ Pt ( en) 2BrZ] ( ClO,) ., (en = H2NCHZCH2NHZ) has been studied as a function of temperature and excitation wavelength. Six features are observed for the symmetric Pt-Br stretch. v,, at low temperature and each shows a distinctly different excitation profile. The 18 1 cm-' component dominates the spectrum with blue excitation while the 168 cm-' component dominates with red excitation. The results help to explain the origin of the previously described dispersion of Y, with excitation wavelength and the unusual excitation profiles that the v, bands of these mixed-valence complexes exhibit.
