✦ Synopsis
The collision dynamics of the
OH+ Ar/He systems have been studied following production of the translationally and rotationally al&ned radical species via polarized photolysis of HsO, at a wavelength of 248 nm. Elastically scattered OH molecules were probed via polarized Fourier-transform Doppler spectroscopy. The manner in which the speed distribution and laboratory speed averaged translational anisotropy of the OH photofragments change with time is well reproduced by a hard sphere collision model. In addition, the degradation of the laboratory speed averaged CL. correlation by collision with argon is best reproduced if the direction of the OH rotational angular momentum vector is conserved throughout an elastic collision encounter.
