Rate Constants of Energy Transfer Between Pyrazine and N2O
Using UV light, we can excite Pyrazine to higher vibrational and translational energy states. By exciting Pyrazine in a system with N2O, we can then observe changes in energy in N2O resulting from bimolecular collisions with Pyrazine. Probing different energy states in N2O with an IR laser allows us to see how much energy is transferred into each state. We can calculate the rate constant of energy transfer to each state by measuring the number of N2O molecules scattered into a state as a function of time and the number of excited pyrazine molecules created prior to the collisions. These rate constants are a crucial part of calculating probability distribution functions, providing information that is needed for accurately modeling bimolecular reactions in complex environments.
