“…The energy dependence of collisional relaxation in highly vibrationally excited molecules has important consequences for the redistribution of energy in high energy environments and impacts the availability of internal energy for chemical reactions. − Information about collisional relaxation of highly excited molecules comes from a number of experimental and theoretical approaches, but truly predictive models do not yet exist. − Unimolecular reactions that take place over deep potential energy wells are particularly sensitive to the distribution for energy transfer events . The interplay between the limiting cases of strong and weak collisions, which is at the heart of the collisional deactivation process, has long been recognized as a key component of the overall relaxation process.…”
