Electron Paramagnetic Resonance Spectroscopy

ELECTRON PARAMAGNETIC RESONANCE (EPR) SPECTROSCOPY AND GEOCHEMISTRY IN TIN EXPLORATION AT RENISON, TASMANIA AUSTRALIA

Rock powder of dolomite samples from the Renison mine area of Tasmania, Australia were analyzed by electron paramagnentic resonance spectroscopy (EPR), Atomic Absorption and Mass Spectrometer to identify alteration related to mineralisation. The least-altered dolomite samples, which are not effected by circulation of diagenetic and hydrothermal fluids are characterised by low Mn and Fe and ...

Demystifying EPR: A Rookie Guide to the Application of Electron Paramagnetic Resonance Spectroscopy on Biomolecules

Electron Paramagnetic Resonance (EPR) spectroscopy, also known as Electron Spin Resonance(ESR) especially among physicists, is a strong and versatile spectroscopic method forinvestigation of paramagnetic systems, i.e. systems like free radicals and most transition metalions, which have unpaired electrons. The sensitivity and selectivity of EPR are notable andintriguing as compared to other spec...

electron-paramagnetic-resonance studies using oxygen-17

Studies of the effect of substitution with 170 on the e.p.r. spectra at 9 and 35 GHz of Mo(V) in the phosphate complex of sulphite oxidase are reported. Substitution of '7O-enriched water for normal water, for samples of the enzymes reduced by sulphite in the presence of normal phosphate, produced no detectable effect on the e.p.r. signal. If phosphate substituted with 170 was used, coupling du...

Pulse Programmer for Electron Paramagnetic Resonance Spectroscopy

The design of a new pulse programmer is presented. It is based on an application-specific integrated circuit (ASIC) and designed to fulfill the requirements of pulse electron paramagnetic resonance (EPR). The pulse EPR ASIC provides a high time resolution (2 ns) and a high channel density (8 channels per chip). The pulse sequences are controlled by a digital signal processor (DSP). The sequence...
