Quantum-State-Resolved Scattering of OCS at the Gas-Liquid Interface: Hyperthermal versus Thermal Vibrational Equilibration Dynamics in Polyatomics
| Author | |
| Abstract |
Shot-noise-limited direct absorption spectroscopy with a high-resolution quantum cascade laser is used to explore translational-to-rovibrational (T → V, R) energy transfer in hyperthermal collisions (Einc ≈ 21(1) kcal/mol) of polyatomic OCS at the gas–liquid interface. Such data provide first evidence for rovibrational quantum state-dependent branching into trapping–desorption (TD) and impulsive scattering (IS) pathways for a polyatomic molecule, with unexpected behavior evident due to novel resolution of vibrational degrees of freedom. |

The Physics Frontiers Centers (PFC) program supports university-based centers and institutes where the collective efforts of a larger group of individuals can enable transformational advances in the most promising research areas. The program is designed to foster major breakthroughs at the intellectual frontiers of physics by providing needed resources such as combinations of talents, skills, disciplines, and/or specialized infrastructure, not usually available to individual investigators or small groups, in an environment in which the collective efforts of the larger group can be shown to be seminal to promoting significant progress in the science and the education of students. PFCs also include creative, substantive activities aimed at enhancing education, broadening participation of traditionally underrepresented groups, and outreach to the scientific community and general public.
