✦ Synopsis

A pulsed, tunable dye laser has been used to escite the O-O band of cis~glyoxal near 4875 A, at pressures from 30 to I50 mtorr, Fluorescence was resolved through a spectrometer and lifetines measured. Rate constants for the quenching of the vibrationless levels of the first excited singlet states of cis-and frans.glyoxal 'uy argon, cyclohexane and glyoxal are presented. Quenching rates of cis-glyoxal are generally two to three times faster than the corresponding rrans rates. A zero-pressure extrapolated lifetime of 0.96 2 0.02 ~.~sec is obtained for cis.glyoxal.
