Electron paramagnetic resonance (EPR) (also known as electron spin resonance (ESR)) studies of molecules with unpaired electrons - primarily organic radicals and transition metal ions. We are interested in a variety of applications of this technique. EPR imaging examines the spatial distribution of unpaired electrons in a sample. We are developing CW, pulsed, and rapid scan imaging methodologies for in vivo applications. Electron spin relaxation times are measured by pulsed EPR techniques. The relaxation times provide insight into molecular dynamics. Measurements at multiple resonance frequencies permit assignment of mechanisms. In rapid scan EPR the magnetic field is scanned through the signal in times that are short relative to relaxation times. The full spectrum is encompassed in each scan, which provides dramatically improved signal-to-noise per unit time for samples ranging from irradiated solids to nitroxide radicals in fluid solution. We are working to develop the next generation of EPR spectrometers taking advantage of improvements in digital electronics
