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,
## Abstract The kinetics of the formation of the photochromic forms B and C of tetramethylβdianthrone has been studied in triacetin and methylcyclohexane/2βmethylpentane at several temperatures. A flash spectroscopy method was developed, which allows the recording of the transient behaviour of the
The rate constant for the quenching of triplet anthracene by molecular oxygen in the presence or absence of polystyrene was measured. The quenching ability is not affected by the presence of polymer.
The rate constants (kHA and klQ) for the hydrogen atom abstraction (HA) and induced-quenching (IQ) processes between triplet benzophenone (3Bp \*) and halogenated toluenes (XTL) were determined by means of nanosecond laser flash photolysis techniques. It was found that the klQ value increased propor
