the optical spectrum band positions and epr parameters (g factors g//, g^ and hyperfine structure constants a// and a^) for vo2+ ions in zn(antipyrine)2(no3)2 are theoretically studied from the complete diagonalization (of energy matrix) method (cdm) and the perturbation theory method (ptm). in the two methods, the contributions from the spin–orbit (so) coupling of central 3dn ion and ligand ar...

The measurement of hemoglobin-nitric oxide (NO) adduct (HbNO) in whole blood by the electron paramagnetic resonance (EPR) method seems relevant for the assessment of systemic NO levels. However, ceruloplasmin and unknown radical species overlap the same magnetic field as that of HbNO. To reveal the EPR spectrum of HbNO, we then introduced the EPR signal subtraction method, which is based on the...

Electron paramagnetic resonance (EPR) is a well-known method for its sensitivity and accuracy in irradiated food detection. Our goal is to analyse the irradiated green coffee by EPR. Arabica beans and grounded coffee was electron beam irradiated up to 40 kGy. The EPR spectra and time dependence of signals were studied. Results were analysed with respect to find a possibility to identify irradia...

High throughput methods for detecting protein interactions require assessment of their accuracy. We present two forms of computational assessment. The first method is the expression profile reliability (EPR) index. The EPR index estimates the biologically relevant fraction of protein interactions detected in a high throughput screen. It does so by comparing the RNA expression profiles for the p...

It is sometimes profitable to measure the longitudinal nuclear spin polarization of He. The method described here takes advantage of the vaporized alkali metal already present in a glass target cell. Long range and short range interactions with polarized He gas result in an “effective” magnetic field felt by the alkali metal atoms. A precisely detectable Zeeman shift in the alkali EPR frequency...
