SOME EFFECTS OF INTRAMOLECULAR VIBRATIONAL ENERGY TRANSFER IN COMPLEX FLUORESCENT MOLECULES

The effects of intramolecular redistribution of vibrational energy on both the fate of an excited complex molecule and the appearance of its electronic spectra are discussed in terms of a three-dimensional energy surface. It is suggested that continuous absorption be used as a criterion for the application of classical methods to intra- and inter-molecular vibrational energy transfer in those cases where fluorescence emission is observed.
