โœฆ Synopsis

The ESR lineshape of spin-correlated radical pairs (RP) diffusing in a small volume is calculated within the sudden perturbation approach for space dimensionalities D = 1, 2, 3. It is shown that in 2D and 3D models the RP spin dynamics are described by a Bioch-type equation quite accurately. A simple formula for the antiphase structure of the ESR lines is derived. The results obtained differ essentially from those predicted in the quasistatic approximation.

Hore and McLauchlan that shortly after their formation geminate isopropylketyl radicals in isopropanol at law temperature ( ~200 K) exhibit ESR spectra with "antiphase" lineshape, i.e. lines with their low-field halves in emission and high-field halves in absorption. It is shown that a theory which

A statistical analysis was performed to determine to what extent an amino acid determines the identity of its neighbors and to what extent this is determined by the structural environment. Log-linear analysis was used to discriminate chance occurrence from statistically meaningful correlations. The

The ESR and ENDOR spectra and hyperfine coupling constants (hfi) of the tertiary butoxyl spin adduct of 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) change markedly, but reversibly, with increase in temperature from 140 to 280 K, and the spectra can be cycled repeatedly between these temperature limits.
