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