Photo-ionization of Aromatic Compounds in Hydrocarbon Glass at 77° K

Abstract

PHOTO-IONIZATION in hydrocarbon glasses has been reported for amines1,2 which are known to possess low ionization potentials. In these cases, photo-ionization is proportional to the intensity of the photolysing light. Photo-ionization has been established by observing one or more of the following: absorption spectra of ions and/or electrons1–3; delayed luminescence4; thermoluminescence3,5; electron spin resonance spectra of electrons5; optical bleaching of electrons and the resulting luminescence5; photoconductivity6.
