The WSU Center for NMR Spectroscopy is a central University facility that provides access to state-of-the-art NMR instrumentation. Electron spin resonance spectroscopy (ESR) or electron paramagnetic resonance (EPR) is a technique for studying chemical species that have one or more unpaired electrons, such as organic and inorganic free radicals or inorganic complexes possessing a transition metal ion. Optical spectroscopy has been enormously useful for exploring the energy levels and excitations of atomic systems at electron-volt energies. It is stabilized against temperature fluctuation by immersion in an oil bath or by forced air cooling.

Spectroscopy is the study of the interaction between light and matter where the absorption and emission of light or other radiation by the matter are studied and measured. A Raman spectrometer was deployed on the Viking landers in 1972 and in other missions. 104104011. << /Length 8 0 R TEMPO is a commercial free radical that has nitroxyl group (N-O radical).

Electron Spin Resonance (ESR) also known as Electron Magnetic Resonance (EMR) or Electron Paramagnetic Resonance (EPR) is a branch of absorption spectroscopy in which radiations having frequency in the microwave region (0.04 – 25 cm) is absorbed by paramagnetic substances to induce transitions between magnetic energy levels of electrons with unpaired spins. Introduction Electron spin resonance (ESR)1 has developed over the past several decades as a technique to provide information on the electronic structure of organic, inorganic, biological, solid state, and surface molecular species. The rotational and vibrational energy levels of the molecule in the sample determine the magnitude of the frequency shifts. HOME.
