โœฆ Synopsis

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 takes into consideration the interradical exchange interaction can account for such a lineshape only under the assumption of an attractive interradical interaction leading to the formation of a cage. The cage dissociation rate W, and the potential well depth UC are estimated from experimental results: W,=3.4x 106s-', UJk,T*66.2.

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 simpl

The antiphase structure (APS) of CIDEP spectra of spin correlated radical pairs in viscous liquids is investigated theoretically in a free diffusion model for relative motion of radicals. A very simple and accurate formula for relative APS amplitude is derived. This formula predicts a very small AP
