Research interests

My research interests are primarily in the experimental investigation of the gas-phase behaviour (kinetics and photochemistry) of species relevant to atmospheric, combustion and fundamental chemistry. These species are typically radicals, short-lived intermediates that drive change.

The chemistry observed in a particular environment is complex as it typically consists of hundreds, if not thousands, of competing processes. Therefore to understand complex phenomena it is desirable to study each process (reaction or photochemical) in isolation, and then test if each of these processes adds up to describe the observed phenomena. In the laboratory, reactions (or photochemistry) are studied in isolation, or as simple as possible, in experiments that principally use lasers, where one laser is used to create and another laser to probe the time profile of the species of interest.

I'm primarily involved in the hands-on running and maintenance of the Dainton laboratory, which has a large number of lasers that can run 6 independent experiments. Each experiment typically uses a high powered UV laser, an excimer laser, to photolyse a suitable precursor to generate the target radical. There are a number of laser schemes available for detecting the target radical, mainly via dye lasers. Laser induced fluorescence (LIF) is particularly efficient for many small species. In the atmosphere the hydroxyl radical, OH, is the principal oxidant, and it can be efficiently detected using LIF, and this is our main method to detect OH in laboratory experiments. The hydrogen atom is prevalent in combustion systems, and it can be efficiently detected at 121.56 nm, the vacuum ultraviolet, VUV. The Dainton laboratory has much experience in frequency tripling the output of a tuneable dye laser to generate VUV and detect H atom via LIF. VUV light is also efficient at ionizing radicals, particularly large radicals that do not fluorescence, and in one experiment it is used with a time-of-flight mass spectrometer to simultaneously probe all the species in a given reaction. There are a number of species that can be probed in absorption, and by capturing visible light from a dye laser between two highly reflecting mirrors - the cavity - provides thousands of passes, path-length, and results in sensitive radical absorption detection, e.g. the HCO radical. In a newly constructed experiment the output of a lamp (200 - 800 nm) is multi-passed to provide time-resolved absorption simultaneously over all wavelengths, and is particularly efficient at detecting the Criegee radical, CH2OO.

The experiments in the Dainton Laboratory are run in collaboration with Paul Seakins and Dwyane Heard, and can investigate reactions over a wide range of temperatures, 40 - 1000 K, and pressures, 0.001 - 5 atmospheres. In addition, I'm a contributor to MESMER, the open source program for calculating rate coefficients through solving the chemical master equation. This program provides a direct way of linking the results from the laboratory to those from theoretical calculations, and hence is able to determine how well a given reaction is understood. It is also able to make predictions on reactions that are experimentally inaccessible.

The following are some recent research highlights:

Using the Laval technique, low temperature kinetic measurements, 40 - 150 K, have recently shown that Quantum Mechanical Tunnelling provides a novel mechanism where reactions that are slow at room temperature, e.g. OH + CH3OH, can be fast and important at temperatures relevant to astrochemistry, Nat Chem, 5(9), 745 - 749.

In the reaction between OH and C2H2 it has been shown that the outcome of the reaction, the products, depends on the percentage of O2 present. This effect is due to O2 intercepting the products of the reaction before they are thermalized, and is known as non-thermal kinetics. This effect may play a significant role in atmospheric chemistry, Science, 337(6098), 1066-1069.

The atmospheric chemistry of amines relevant to carbon capture storage has been investigated, where their removal kinetics and the primary products of reaction have been determined, Environ Sci Technol, 48(16), 9935-9942.

The chemistry of dimethyl ether (DME) is a potential alternative fuel in the development of clean vehicle engines. The oxidation of DME occurs via the OH radical, and via monitoring OH the energies of the key species, RO2 and QOOH, have been pinpointed, J Phys Chem A, 118(34), 6773-6788. It is the reaction between QOOH and O2 that leads to 2 OH, branching, which results in explosion, and this is currently being explored.

The Criegee intermediate is the long postulated intermediate formed in the ozonolysis of alkenes. Even though much effort had gone into its direct observation from ozonolysis reactions, it has only recently been directly observed. In a recent study using the multiplexing absorption setup it was shown that the most important Criegee in the atmosphere CH2OO is predominantly removed by the water dimer, (H2O)2, PCCP, 17(7), 4859-4863.

An ongoing grant is investigating the photochemistry of peroxy radicals, RO2, where the most important is R = OH-isoprene. Field measurements have highlighted that in tropical, forested environments the hydroxyl radical, OH, concentrations are up to an order of magnitude higher than can be explained using our current chemical knowledge. This project speculates that RO2 photolysis is an explanation for this missing OH. The project involves a three laser experiment: the first to make RO2, the second to photolysis over a range of wavelengths and the third to probe the OH; a multiplexing absorption experiment to determine the absorption spectrum of the RO2, which is the upper limit on the OH yield; and a flow tube experiment to make the RO2 and laser to photolyse it, followed by a very sensitive FAGE laser to probe the OH.
