Persistent Infrared Spectral Hole-Burning for Impurity Vibrational Modes in Solids.
Abstract
One unusual group of excitations in which persistent spectral hole burning has been observed consists of infrared vibrational transitions of impurity molecules in solids. Examples include 1,2,-difluoroethane in rare gas matrices, perrhenate ions in alkali halide crystals, and most recently, cyanide and nitrite ions in KBr. The hole formation mechanisms involve molecular reorientation or conformational changes at low temperatures induced by excitation of an internal vibrational mode of the impurity molecule. Keywords: Persistent spectral hole burning; vibrational mode; infrared; reorientation.
