Lecture: «Ultrafast transient absorption spectroscopy studies of radical and photoredox reaction intermedia»
Prof. Andrew Orr-Ewing (School of Chemistry, University of Bristol)
CiQUS Seminar Room - 17:00 h.
The research in Orr-Ewing's group uses several different types of lasers (including nanosecond and femtosecond pulsed lasers, and mid infra-red cw lasers) to study chemical reactivity, atmospheric chemistry, methods of trace gas detection, optical properties of aerosol particles, and molecular spectroscopy and photochemistry. The group uses ultrafast transient absorption spectroscopy to study chemical reaction dynamics in liquids, velocity map imaging to explore quantum-state resolved reactive scattering in the gas phase, and cavity enhanced spectroscopy methods for a variety of applications in atmospheric chemistry and aerosol science. In addition, computational methods such as ab initio electronic structure theory and molecular dynamics to aid the interpretation of experimental measurements are employed.
