Abstract

Anti-Stokes resonance Raman spectra for F-center CN-defect pairs in KBr are presented. Both the Dexter-Forster (i.e., dipole-dipole interaction) and supermolecule models are considered for the calculations of electronic-to- vibrational energy-transfer processes. Our studies suggest that the property of the defect molecule is more important than the structure of the host crystal in the determination of the electronic-to-vibrational energy-transfer processes of F-center molecular-defect pairs in alkali halides.
