Phonon selective low temperature photochemistry in alcohol glasses

Abstract

The molecule dihydroxyanthraquinone, which exhibits reversible, light-induced proton transfer is chosen for photo-chemical hole burning experiments in alcohol glasses. The experiments show the novel feature of a phonon selective photo-chemical mechanism, which verifies experimentally that the different sites in glasses have rather large variations in electron-phonon coupling strength. © 1980, All rights reserved.
