The fine structure branching ratio of chlorine atoms produced in the photodissociation and predissociation of HCl was measured for excitation energies between 51 800 and 83 800 cm Ϫ1 . The branching ratio between 60 000 and 70 000 cm Ϫ1 is in good agreement with the calculations of Alexander et al. ͓J. Chem. Phys. 99, 1752 ͑1993͔͒, converging to the statistical limit at high energy. Predissociation of electronically excited bound states display a surprisingly rich behavior, demonstrating that
