27. Since the (0,2) singlet-triplet splitting is much larger than the energy scale of the SOI (Ref.), the (0,2) states are reasonably described as triplets T0,± (0,2) and singlet S (0,2). The nature of the (1,1) levels could however be strongly modified by SOI.
28. The minimum at t (1,1) 160 ns is also observed for different total cycle periods and in schemes, where only t (1,1) is varied. The origin is not fully understood, but it does not affect the analysis of the relaxation process above 200 ns.
