Abstract
Photoexcited triplet states of anthracene in a glassy toluene matrix were investigated using pulsed UV–laser photoexcitation and pulsed electron paramagnetic resonance spectroscopy. The triplet lifetime, the triplet relaxation rates between the high-field eigenstates and the populations of the triplet sublevels are quantitatively analysed. High-quality data allows for supporting the former conclusion that excitations into the individual zero-field components proceed via independent channels.
