Abstract

The fine structure branching ratio and Doppler profiles of photofragment Cl ($^{2}P_{j}$) atoms from photodissociation of CINO around 236 nm in the A band have been measured by the two photon resonance enhanced multiphoton ionization technique. The measured branching ratio, $Cl^{\ast} (^{2}P_{1/2})/Cl (^{2}P_{3/2})$ is $0.18{\pm}0.02$. The Doppler profile of Cl is well reproduced assuming that one of the two components in the photofragment translational spectra reported by Haas, Felder, and Huber [Chem. Phys. Lett., 180, 293 (1990)] should correspond to Cl and that an anisotropy parameter $\beta$ for the angular distribution is 0.45. The results suggest that CINO dissociation in the A band should consist of at least two non-crossing electronic states which correlate to the formation of $Cl^* and Cl, respectively.
