Abstract
- Two‐dimensional (2D) Fourier‐transform (FT) electron paramagnetic resonance (EPR) nutation experiments were done in order to verify anomalous flip‐angle dependence of a FT–EPR spectrum of a photochemically generated spin‐correlated radical pair (SCRP). It was demonstrated by both the experiment and theory that the signals of SCRP have additionally higher and lower nutation frequencies than that of a free radical. This spectroscopy provides a direct spectroscopic evidence of spin‐correlation within SCRP, and enables one to partially separate SCRP signals from free radical signals in the 2D EPR spectrum.
