Collisional Energy Transfer Extrapolation from Large deltaE Regions
Collisional energy transfer is a key component to understanding the kinetics of complex chemical reactions; however, current understanding is still insufficient to model complex chemical environments. The key energy transfer information necessary for modeling of these complex environments is P(E,E’), the energy transfer probability distribution function, which describes the probability of a molecule initially at energy E’ having an energy E following a single collision with another species. Currently measurements of P(E,E’) from large deltaE regions are extrapolated to small deltaE regions to obtain a “complete” P(E,E’). Our efforts are focused on understanding if this is an accurate representation by directly measuring a larger range of energy transfer events and comparing P(E,E’) obtained in this approach to that obtained by extrapolation of the large deltaE region.
