Abstract
Substitution of the cydopentadienyl radical introduces a splitting of the originally degenerate $\bar{X} ^{2}E_{1}^{\prime\prime}$ state due to lowering of the $D_{5h}$ symmetry to $C_{2v}$ We have obtained rotationally resolved laser induced fluorescence spectra of the fluoro- and chloro- substituted cyclopentedienyl radicals in a supersonic free jet expansion. The radicals were generated by ArF photolysis of 2-fluoro and 2-chloroanisoles. A detailed rotational analysis and the resulting implicarions for electronic state assignments and molccular structure will be presented along with a discussion of the effect of various substitutions on the electronic structure of the $C_{5}H_{5}$ ring
