You will study the dynamics of inelastic energy transfer and reactive scattering relevant to atmospheric chemistry, combustion or astrochemistry using state-of-the-art experimental and theoretical methods, to determine the underlying mechanisms and improve our understanding of chemical interactions in these important environments.
Detailed understanding of molecular collisions, and the resulting energy transfer and/or reaction is vital to improved modelling of a wide range of important chemical environments, including planetary atmospheres, combustion and plasma systems and astrochemistry. In this project, you will apply state-of-the-art chemical dynamics techniques; Crossed-molecular-beam scattering coupled to high-resolution laser spectroscopy and velocity-map ion-imaging for detection, and will study the dynamics of molecular collisions. One strand of work will involve inelastic energy transfer of radicals important in practical environments e.g. NO and OH, with rare gases and small molecules (Nat. Chem. 10, 1148 (2018)). By comparing measurements of differential scattering cross sections, correlated energy transfer, and product rotational angular momentum polarization, to quantum and classical scattering calculations, you will perform critical tests of current theoretical models. Another strand will feature reactive collisions of O-atoms and OH with saturated, unsaturated and functionalized hydrocarbons. These systems display competition between abstraction and addition pathways. Measurements of product branching ratios, energy disposal and scattering angle distributions, can help to disentangle these multiple pathways. These measurements will connect directly to our complementary on-going experiments on reactive oxygen chemistry at gas-liquid interfaces.
