✦ Synopsis

A tunable. pulsed dye Iaser with output in the region of 5750 to 6000 X was used to excite rotationally cooled NO1 which was produced by expansion in conjunction with argon carrier gas through ;t supersonic nou!e. The resulting timeresoked fiuoresccnce excitation spectra were used to measure the lifetimes of various vibronic bands of NOz('Bz)-The lifetimes measured were in the region of 15 to 40 ps which were shorter than those obtained from eelI experiments. For eachindividual excitation wavelength, only a single exponential decay was observed from very early times through 2.50 ps.
