Abstract: The use of scattering experiments in atmospheric studies has proved useful in understanding the dynamics of the catalytic ozone destruction cycle. By using millimeter and sub-millimeter wavelengths, we can probe bimolecular reaction systems for translational, rotational, vibrational, and electronic energy distributions thru pure rotational spectroscopy. The focus of this research is on the reaction between iodine, bromine, and ozone due to their roles in the catalytic ozone destruction cycle. For this research we studied the X + O3 (X= I and Br) and O(1D) + X (X= I2, Br2, N2O, and CHCl3) reactions using single and crossed molecular beam techniques. The apparatus contains two independently rotatable arms, capable of changing collisional energies in relation to arm angle. Though no product signals have been detected at this time, critical experimental methods have been developed that can be optimized in the future.
