Angle resolved UV photoelectron spectra of titanyl phthalocynine monolayer film on graphite

Angle-resolved photoelectron spectra were measured for a well-ordered monolayer film of litanyl phthalocyanine (OTiPc) prepared on a cleaved graphite surface using synchrotron radiation. The observed photoelectron angular distributions were analyzed by a calculation using the single-scattering approximation combined with molecular orbital calculation. The molecular orientation of the OTiPc monolayer on graphite was estimated quantitatively. (C) 2006 Elsevier B.V. All rights reserved.
