The photochemistry of maleimide in aqueous solution is governed by the coexistence of up to three different triplet states, the keto triplet (lambda(max)=250, 330 nm, lambda(min)=290 nm, pK(a)=4.4+/-0.1, tau=5 micros), the deprotonated or enolate triplet (lambda(max)=360, 260 nm, lambda(min)=320 nm,
The photoexcitcd triplet states of chlorophyll a and b are studied by the EPR method at -85 K using modulated ii&t excitation. Both compounds show anomalous EPR line intensities and transient kinetics, indicating e!ectron spin polxi~ation (ESP) in the photoexcitcd triplet state. EPR studies, using h
