LASER FLASH PHOTOLYTIC DETERMINATION OF QUENCHING RATE CONSTANTS FOR TRIPLET SENSITIZERS BY ALKYL PEROXIDES
WOODS, TREACY LYNN

Rate constants for quenching of triplet sensitizers by several alkyl peroxides were measured by laser flash photolysis in benzene solution. Because these rate constants decrease monotonically with sensitizer triplet energy, electronic energy transfer is concluded to be the likely quenching mechanism. A rough correlation exists between quenching rate constants and peroxide thermal lability. Finally, the computer interfaced laser flash photolysis apparatus which was used in these measurements is described in detail.
