Abstract

The D1-D0 electronic spectrum of jet-cooled cyanocyclopentadienyl (C5H4CN) radical, produced by excimer laser photolysis of 1,3-cyclopentadiene-1-carbonitrile (C5H5CN), was measured by laser-induced fluorescence (LIF). The LIF spectrum was identical to that of radicals produced by photolysis of phenyl isocyanate and o-chloroaniline, which had been assigned to phenyl nitrene. This result shows that the nascent radical product in the photolysis of o-chloroaniline and phenyl isocyanate is isomerized to C5H5CN and the final product of C5H4CN radical is derived via the second photolysis. The rotational contour of the 0-0 band of the C54CN radical, at 27143 cm-1 (368.3 nm), is also presented. The electronic transition is A-type and π electron transition, and the symmetry of both the ground and excited electronic state is 2B1 (of the C2v point group).
