Anisotropic yields of the signalling state, S, for various model radical pairs. (a) and (b) [FAD^•− Z^•] radical pair with N5, N10, H6, H8 and Hβ in FAD^•− and no hyperfine interactions in Z^• or the scavenger. (c) and (d) [FAD^•− WH^•+] radical pair with N5 and N10 in FAD^•− and N1 in WH^•+. The scavenger had a single isotropic ¹H hyperfine interaction equal to that of the H4 proton in the ascorbyl anion radical⁵⁰. (e) and (f) [FAD^•− WH^•+] radical pair with N5 and N10 in FAD^•− and N1 in WH^•+. The scavenger, which reacted with WH^•+, was modelled on FAD^•− and included the N5 and N10 hyperfine interactions.
