Ultrafast High Harmonic, Soft X-Ray Probing of Molecular Dynamics
Abstract
A three-year experimental investigation of the photochemistry and molecular dynamics of ionic liquids in vapor phase and aerosol is completed. The photochemistry and thermodynamics of ionic liquids are studied using the quasi-continuous vacuum ultraviolet light of the Advanced Light Source at Lawrence Berkeley National Laboratory. The molecular dynamics is also studied using short soft x-ray pulses that were produced by the method of pulsed laser high order harmonic generation. A collaboration with Steven Chambreau and Ghanshyam Vaghjiani produced results on the thermodynamic, kinetic, ultrafast, and photochemical properties of ionic liquid molecules, especially those of interest for propulsion. Also a new experimental setup has been constructed for the investigation of ultrafast photoinduced processes of charge localization at the surface of photocatalytic materials. Understanding ultrafast photoinduced processes at surfaces is a defining principle that will guide advances in the next generation of catalysts to produce storable fuels from sustainable inputs as desired by the Air Force.
