Abstract
The velocity distribution and alignment of the NO fragments produced by UV photodissocn. of nitrosobenzene have been studied by LIF measurements of Doppler profiles and polarization. The S2 and S3 states of nitrosobenzene were excited by irradn. into the first and second UV absorption bands at 290 and 266 nm, resp. No alignment could be detected.

Abstract
The velocity distribution and alignment of the NO fragments produced by UV photodissocn. of nitrosobenzene have been studied by LIF measurements of Doppler profiles and polarization. The S2 and S3 states of nitrosobenzene were excited by irradn. into the first and second UV absorption bands at 290 and 266 nm, resp. No alignment could be detected. All Doppler profiles studied with rotational quantum nos. ranging from j = 6.5 to 29.5 can be fitted by Gaussians, their widths indicating thermal velocity distributions with an av. velocity nr.m.s. < 1000 m/s. The authors interpreted this as indication of fast electronic relaxation of the excited nitrosobenzene followed by extensive rotational and vibrational equilibration prior to dissocn.
