State-Resolved Dissociative Chemisorption Dynamics with RAIRS Product Detection
Laurin Joseph, Sally Shepardson-Fungairino, and Arthur Utz
State-resolved molecular beam molecular beam experiments use energy and quantum-state selected reactants to understand how specific molecular motions (molecular vibration, rotation, and translation) promote transition state access and chemical reactivity. They also generate experimental data that serve as rigorous benchmarks for DFT-based predictions of reaction barriers and dynamics.
We are currently updating one of our differentially pumped molecular beam reaction chambers to incorporate Reflection Absorption Infrared Spectroscopy (RAIRS) detection of surface-bound reaction products. This capability will allow for real-time, coverage-dependent studies of the reactions occurring on metal surfaces, will provide structural fingerprints of reaction products, and will open the door to the study of larger, more chemically complex, reactant molecules. This poster will survey our progress to date and present preliminary reactivity data for methanol dissociation on a Ru(0001) surface.
