EPR spectroscopy of 4f- and 5f-complexes


Project Description

EPR (Electron Paramagnetic Resonance) spectroscopy is a powerful but underused tool to study f-block (lanthanide and actinide) complexes. This project will build on work in the Manchester EPR and Molecular Magnetism groups, exploiting EPR and complementary methods towards developing a detailed understanding of the electronic structure of f-element compounds. The ultimate goal is to rationalise important physical behaviour, for example the nature of the chemical bonding to ligands, or magnetic (electron spin) relaxation behaviour. The PhD student will be trained in use of state-of-the-art EPR spectroscopy (both continuous wave and pulsed methods), magnetometry, and in modelling such data.

Academic background of candidates
Applicants are expected to hold, or about to obtain, a minimum upper second class undergraduate degree (or equivalent) in Chemistry, Physics or related science. A Masters degree in a relevant subject and/or experience in spectroscopy is desirable.
