This paper presents a theoretical model which describes correlation effects in nonresonant photochemical holes. The model calculations are compared with experiments of photochemical hole burning (PHB) in electronically excited vibrational states of 1,4-dihydroxyanthraquinone (DAQ) in alcohol glass matrices. Vibrational hole burning shows some specific features such as the occurrence of several nonresonant holes in the electronic origin which differ considerably in their widths and integrated optical density from the resonant hole. The difference in linewidth is related to a vibrational inhomogeneity which is superimposed on the observed relaxation broadening. The experiments show that the vibrational inhomogeneity is not uniform but varies with the vibrational state.
