Research Fellow in Experimental Gas Phase Kinetics

University of Leeds - Faculty of Mathematics & Physical Sciences - School of Chemistry

Are you looking to apply your skills in experimental physical chemistry to a study of the role of Criegee intermediate decomposition and reaction with water vapour in atmospheric chemistry?

As a Research Fellow in Experimental Gas Phase Kinetics you will join a 3-year NERC-funded project focused on understanding the chemistry of Criegee intermdiates in the troposphere, and particularly on the role of unimolecular decomposition and reaction with water vapour. Criegee intermediates are reactive species produced in the atmospheric oxidation of unsaturated volatile organic compounds by ozone, in ozonolysis reactions. Until recently, direct experimental investigations of Criegee intermediate chemistry and kinetics has proved challenging. In this role you will use recently identified photolytic sources of Criegee intermediates to investigate the kinetics and product yields of key Criegee intermediate reactions in the troposphere, using a combination of broadband time-resolved UV absorption spectroscopy and quantum cascade laser (QCL) IR absorption spectroscopy. You will also develop UV instrumentation to enable the direct detection of Criegee intermediates in ozonolysis reactions in the Highly Instrumented Reactor for Atmospheric Chemistry (HIRAC). The resulting data will feed into models of tropospheric chemistry using the Master Chemical Mechanism (MCM) to assess the impacts on atmospheric composition.

You will have a PhD in Experimental Physical Chemistry and/or Atmospheric Chemistry, the ability to carry out complex physical chemistry experiments independently and a good background knowledge of contemporary research in laboratory studies of Atmospheric Chemistry.
