Title

Comparison of N2O and CO2 collisions

Abstract

Modeling complex gaseous reactions requires fundamentally understanding the elementary factors affecting each step in the mechanism including collisional energy transfer events, however despite years of study there is no universal model to describe collisional energy transfer. Work in our lab has helped to develop an empirical model based on CO2 collisions that relates how vibrational state densities change with the change in the energy transfer probability distribution function, P(E,E’). However, it remains unclear if this approach can be extended to other bath systems. We have started to measure energy transfer and P(E,E’) for N2O and  pyrazine collisions to determine if the model can be applied generally. We are also comparing results from the N2O collisions to systems involving other bath molecules (CO2, H2O and HCl) to understand bath characteristics influence P(E,E’).
