Popis:	Photophysical and photochemical techniques were used to investigate the photodegradation of Bisphenol A polycarbonate (PC), with diphenyl carbonate as a model compound. UV excitation of these compounds leads to a fluorescence band with a maximum around 300 nm. The triplet state of PC is also observed both by transient absorption and by phosphorescence studies. The PC triplet in CH 2 Cl 2 solution interacts with oxygen, ferrocene, trans-piperylene, and perylene with rate constants of 6.25×10 8 , 2.89×10 8 , 3.05×10 8 , and 5.60×10 8 M -1 s -1 , respectively
