This $100,000 Project Grant award from the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) will support a postdoctoral research fellowship project to study the fate of organic peroxy radicals in the troposphere. The key objectives are to (1) determine if the peroxy radical self-reaction proceeds via a tetroxide intermediate, (2) accurately model the energetics and kinetics of this self-reaction, and (3) understand how peroxy radical structure impacts fragmentation, termination, and dimerization in the self-reaction. The research will employ IR action spectroscopy techniques to detect the tetroxide intermediate and measure its decomposition kinetics, as well as chamber experiments to characterize product distributions. In addition to the research, the project will engage in science outreach programs and mentor graduate and undergraduate students. The award period runs from September 1, 2024 to August 31, 2026.
