Abstract

 We have applied the technique of picosecond laser spectroscopy to study the photodissociation of
 nitrobenzene at room temperature and 100 mTorr. Three different photolysis pulses, 2 = 250, 266, and
 280 nm, with a duration of 20–25 ps, were used. The NO photofragment was detected via LIF between
 1 = 220 and 250 nm. The profile of rotational population distribution shows a dependency on the photolysis
 wavelength and the delay time. The observed rotational population distributions are non-Boltzmann
 and bimodal for v = 0, 1, and 2.
