Abstract

Oxygen enhancement of Stern-Volmer plot slopes for the quenching of benz[a]anthracene fluorescence by cis-1,3-pentadiene in benzene is shown to reveal the presence of a reversibly formed exciplex in this system. In establishing a relationship between experimental lifetime and quantum yield data and the rather complicated rate laws, an iterative least-squares analysis method has been applied which should find general applicability to problems of fitting photochemical kinetic data. The method is also applied to the system benz[a]anthracene-7-d/m-1,3-pentadiene.
