A mixture of methane and chlorine molecules in a helium carrier is expanded into a vacuum chamber using a pulsed valve. Polarized laser photolysis of Clz at 355 nm is used to produce Cl(\*P,,2) with a sharply peaked speed distribution and a known angular distribution. Methane molecules are excited i
