Exposure of dilute solutions of dimethylsulfide, methanethiol, tetrahydrothiophene, terbutyl and diterbutyl-sulfides, dimethyl-disulfide, and diterbutyldisulfide, in freon at 77 K to /sup 60/Co ..gamma.. rays gave the corresponding cations. From the reported ESR spectra, g tensors were obtained. It was found that both sulfide and disulfide cations exhibit ...

EPR spectroscopy has proven to be an indispensable tool in elucidating the structure of metal sites in proteins. In recent years, experimental EPR data have been complemented by theoretical calculations, which have become a standard tool of many quantum chemical packages. However, there have only been a few attempts to calculate EPR g tensors for ...

Design of spin labels inside for possible molecular spintronics, which contains 1D spin chain filling single-walled carbon nanotube (SWCNT) with magnetic endohedral fullerenes of 14N@C60, has been suggested. Electronic structure and magnetic properties of 14N@C60-SWCNT armchair for chiral index (n, n) n=9-13 in contrast with SWCNT and 14N@C60 were characterized. Especially, influence of the SWCNT ...

The effects of applied electric fields on the magnetic parameters of a nitroxide spin label have been calculated using an intermediate level of Rayleigh-Schr�dinger perturbation theory based on unrestricted Hartree-Fock ab initio calculations. The theory is tested for selected simple model organic radicals and gives electronic ...

An electron spin resonance (ESR) study of phosphorus centered electron capture radicals trapped in single crystals of substituted diphosphine disulfides (R/sub 2/P(S)P(S)R/sub 2/, R = Me, Et, Ph) irradiated with x rays at 77 K is reported. The principal values and direction cosines of the hyperfine and g tensors were determined. It is shown that in all ...
