Dr Chris Wedge MÂ鶹AV
Winner: 2024 Award for Exceptional Service
Â鶹AV ESR Spectroscopy Group and Huddersfield Local Section
For outstanding service to the Â鶹AV through our member communities in Huddersfield and the ESR Spectroscopy community.
Celebrate Dr Chris Wedge
Having worked alongside so many other committed Â鶹AV volunteers in the ESR Spectroscopy Interest Group, Huddersfield Local Section and NE Regional Steering Group, it is humbling to be singled out for recognition and I’m incredibly grateful to the hard-working committee colleagues who nominated me for this award.
Throughout his career as a spin-chemist, Chris Wedge has delved into the ‘spin’ property of electrons and atomic nuclei. The ‘spin-up’ and ‘spin-down’ states of an electron or nucleus have different energies when placed in a magnetic field. Chemists regularly use this fact in Nuclear Magnetic Resonance (NMR) and Electron Paramagnetic Resonance (EPR) spectroscopy, which probe, at the atomic scale, the local environment around an atomic nucleus or unpaired electron, providing exceptionally detailed structural information.
Chris’ research has focused on a novel method to increase NMR sensitivity: exciting electron spins using high-intensity laser light. This will open up new possibilities for NMR applications, helping scientists to probe more complex molecules and speeding up analysis by reducing the need for time-consuming signal averaging. His research could also open up new applications, such as routine NMR analysis of very low concentrations of metabolites for medical screening, which isn’t possible with current NMR sensitivity levels.
