Active Spectrum's Micro-ESR spectrometer is a portable (10 kg), X-band (9.7 GHz) CW benchtop electron spin resonance spectrometer. The Micro-ESR is an ideal tool for teaching undergraduate chemistry and physics labs. This instrument enables classroom demonstrations of both simple topics such as the role of free radicals in everyday life to far less intuitive subjects including chemical bonding, electron density, spin-orbit coupling, spin-spin exchange, and forbidden transitions. The spectrometer also allows user control over many important parameters, so students can experiment with different acquisition schemes. The Micro ESR is thus ideal for an instrument lab. All data are automatically saved, and can be imported into any spreadsheet for additional processing or analysis. Offline processing software can also be used to analyze and post-process data, perform quantitative analyses, simulations and other basic functions.
