摘要：

HCl was photodissociated by ultraviolet (uv) radiation at 193.3 nm. Time-of-flight spectra of the hydrogen atom fragment provided the spin-orbit state distribution of the chlorine fragment, [Cl(P-2(1/2))]/[Cl(P-2(3/2))] = 0.69+/-0.02, in excellent agreement with recent theoretical studies. The H atom angular distribution studied by changing the uv photolysis laser polarization confirmed a dominant A (1) Pi<--X (1) Sigma(+) electronic transition in the photoexcitation process (beta = -1.01 +/- 0.04 and beta* = -0.94 +/- 0.07).
