The anomalous flip-angle dependence of the Fourier-transform EPR spectrum of photochemically generated spin-correlated radical pair (SCRP) was verified by means of a two-dimensional FT EPR nutation technique. The 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 analyses, including off-resonance effects, are made to explain the experimental results.
