Welcome

Welcome to the EPR pages of the Millimetre wave and EPR group in the School of Physics and Astronomy at the University of St Andrews, Scotland. Electron Spin Resonance (also known as Electron Paramagnetic Resonance, or EPR) is a spectroscopic technique that can provide useful information on the structure and constituents of many systems involving un-paired electrons. It has a tremendous range of applications from the determination of protein structures to the characterisation of spin defects in semiconductors. An introduction to EPR, and high field EPR in particular, is presented here. We undertake research at EPR frequencies from 23GHz to 270GHz and are well known for our state-of-the art high-field quasi-optical systems. In this respect, we benefit from being able to apply our knowledge of mm-wave instrumentation to EPR systems.

These pages provide an introduction to EPR in general and our work in particular. Information about various aspects of the group may be found using the menu to the left or the links above. General enquiries should be directed to the group leader, Dr Graham Smith.
