The resonance Raman spectra of platinum phthalocyanine (PtPc) in glassy and liquid alpha-chloronaphthalene were recorded in the region 200 $cm-1$ to 1600 $cm-1$ at 77 and $300\circ K$ . Excitation into the (0-0) and higher vibronic absorption regions shows that in the (0-0) transition most of the symmetric modes are resonance-enhanced while only parts of those modes occur in the higher vibronic transitions. We also conclude that the 587 nm transitions is a (0-1), and not a (0-2) band, as is generally believed. Our depolarization studies show ratios greater than 3/4, but much less than infinite. This suggests that PtPc deviates from a strict $D4h$ symmetry.
