Abstract
The anomalous flip-angle dependence of the Fourier-transform EPR spect rum of photochemically generated spin-correlated radical pair (SCRP) w as verified by means of a two-dimensional FT EPR nutation technique. T he SCRP signals were partially separated from free-radical signals in the 2D EPR spectrum; SCRP showed additional higher and lower nutation frequencies compared with those of the free radical. Theoretical analy ses, including off-resonance effects, are made to explain the experime ntal results. (C) 1995 Academic Press, Inc.
