Figure 6.
For kS = kT, it can be seen in (a) that the low field effect occurs for 0 < k ≤ 0.5A for A = ω = 50 G = 0.14 ns−1. Setting k = 0.2A = 0.028 ns−1, it can be seen in (b) that the increase in triplet yield when ω and A are comparable only occurs for times much longer than the lifetime of the radical pair.
