The Cl(2P3/2) and Cl(2P1/2) photofragments produced by the photolysis of Cl2 at ~3.5 eV, are detected using (3+1) and (2+1) resonance enhanced multiphoton ionization and their velocity distributions are measured using ion imaging. The measured photofragment translational energy distributions yield a bond dissociation energy of D0=2.474±0.020 eV for ground electronic state Cl2(X1Sigmag). The angular distributions yield anisotropy parameters of beta(2P3/2)=–0.87±0.05 and beta(2P1/2)= 1.78±0.05 irrespective of the detection process. The branching ratio [Cl(2P1/2)]/[Cl(2P3/2)] is estimated at 8±1%. ©1997 American Institute of Physics.
