Abstract
A reversible temperature dependence of ultraviolet photoelectron spectra was observed for a polycrystalline violanthrene A thin film between 255 and 393 K. A decrease in the linewidth of the lowest-energy peak with decreasing temperature was understood in terms of the interaction of the photoinduced molecular cations with low-energy vibrational modes in the solid film just as in the case of cumene studied by Salaneck et al.
