Exponentiating trajectories and statistical behavior: Three dimensional K+NaCl and H+ICl

Abstract
The dynamic origin of statistical behavior in three dimensional bimolecular collisions is explored using the exponentiating trajectories technique; NaCl+K and H+ICl are explicitly considered. The reported results provide further evidence that statistical product distributions are associated with trajectories characterized by extensive exponential divergence of initially adjacent phase space neighbors. A technique for testing the statisticality of product distributions is introduced and its role as a numerical method for general trajectory studies of long‐lived dynamics is discussed.
