Abstract

Photoelectron spectra are presented for matrices formed by co-condensation of organic halides and atomic zinc beams. For high halide concentrations the spectra are consistent with those obtained from molecular solids, i.e. with the formation of large molecular clusters. Charging effects are absent because of the presence of the conducting zinc matrix. Ionization energies are calibrated with reference to the Zn3d^-1 level and display small relaxation shifts with respect to gas phase spectra. These are due to polarization of molecules surrounding the cation formed by photoionization. The process of co-condensation provides a method for obtaining the photoelectron spectra of molecular solids which would normally present problems due to surface charging.
