Spectroscopy and Dynamics

Developing and utilising spectroscopic techniques, including electron paramagnetic resonance and cavity enhanced spectroscopy as well as modern computational methods, for application to species of chemical and biological interest, such as understanding the structure and dynamics of reactive intermediates, catalysts and biomolecules.

The focus of our research interests lie in the development and application of advanced spectroscopic techniques, coupled with fundamental theoretical research into electronic and molecular structure. Key strengths include Electron Paramagnetic Resonance (EPR) and laser based cavity enhanced spectroscopy, which are used to elucidate the mechanisms and properties of transient species of relevance to a wide range of chemistry. Theoretical work includes development of new methods for improving the accuracy and reliability of first-principles calculations, applied to the prediction and understanding of molecular structure and reactivity, and inter- and intra-molecular non-covalent interactions. Much of our work is performed in collaboration with other research sections, including Catalysis & Interfacial Science, Biological Chemistry, and Molecular synthesis.


The grouping has a wide range ofresearch interests, including:

Applicationsof Electron Paramagnetic Resonance (EPR) spectroscopy for:

  • Mechanistic understanding of reaction pathways in homogeneous catalysis.
  • Investigating visible light photocatalysis of metal oxide systems.
  • Detecting and probing the role of free radical intermediates in selective catalytic oxidation.
