On irradiation in solution in hydrogen-donating solvents, methyl and ethyl pyruvale react through their excited singlet and triplet states to yield a pair of isomeric radicals. Each isomer is formed via both pathways, but in some solvents one is produced predominantly from the singlet state and the

Time-resolved and steady state equations for successive singlet and triplet quenching by the same quencher in micelles are developed. The model assumes that: (i) the quencher can distribute between micellar and aqueous phases, (ii) the probe is completely micellized, and (iii) the distribution kinet
The dynamic behavior of the second excited singlet state of QCS has been investigated for the first time in liquid solutions. In perfluoroalkane solvents strong B-ji. fluorescence (@f up to 0.077) 1s observed when the molecule is excited to bound vibrational states. s lifetimes of up 10 2.8 ns are o
