We have generated the p-chlorobenzyl radical in supersonic free expansion, and measured the laser-induced fluorescence (LIF) excitation spectra and LIF dispersed spectra from single vibronic levels (SVL). Based on an analysis of the dispersed spectra, we find the two band origins, spaced only 94 cm - 1 apart, of the D 1 1 2 A 2 - and D 2 2 2 B 1 -D 0 1 2 B 1 transitions in the excitation spectrum. We also observe interstate level mixing between the 6b and 12 vibronic levels of the D 2 and D 1 states, respectively, in the excitation spectrum, and the vibronic coupling is analyzed using a simple model within the Born-Oppenheimer (B-O) approximation.
