Fig. 2

a–c Delay time (td) dependence of the TREPR spectrum obtained by the depolarized 450 nm laser irradiation of WT XlCry-DASH at 120 K, showing E/A/E/A patterns. d The spin correlated radical pair (SCRP) levels (|1>, |2>, |3>, and |4>) via the superposition and subsequent decoherences by the interaction between the singlet (S) and T0 (|0>) states. The red arrows correspond to population relaxation determined by the rate of 1/T23 between the |2> and |3> levels contributed by J-modulation.
