MATRIX-ISOLATION IN PHOTOELECTRON-SPECTROSCOPY

A range of volatile inorganic species have been trapped in a zinc matr ix using the process of co-condensation and their UV photoelectron spe ctra have been recorded. These are seen to correspond to broadened ver sions of the molecular spectra with ionization energies subject to sma ll polarization shifts. Differences in the ionization energies measure d for low doses of condensate and those measured for higher doses are interpreted in terms of of isolation of small and large clusters withi n the zinc matrix.
