Electron spin resonance

Abstract

The technique variously known as Electron Spin Resonance (ESR) or Electron Paramagnetic Resonance (EPR) continues to find important applications mainly in the Biomedical, Materials and Environmental Sciences. Among the advances which feature information gleaned through its agency, are studies of enzymes and membranes, conductive polymers and novel materials, fuel cells, antioxidants, environmental samples, catalysts and photocatalysts, spin-trapping agents, spin-probes and spin-labels. High-field methods are particularly useful in obtaining improved resolution of overlapping signals and the interpretation of many systems had benefited from the use of Density Functional Theory (DFT) calculations.
