โฆ Synopsis
A method for determination of rates of non radiative energy transfer in assemblies of identicai tluorophorcs, ic described. The method is npplic;lble to systems in which migration of energy by twnst'er is much f'astrr than by difcusion. rcgardlcss of the mechanism of transfer or the type ot' order in the system. The use of the mrthod is dcmonstratt'd in two miccllar systems.

A theory of intramolecular non-radiative transitions is proposed for gaseous small molecules. The theory explains three experimental features: the linearity of the Stern-Volmer equation, the Douglas effect, and the fact that the non-radiative rate is faster in a gas than in condensed media.
