pH dependence of the recovered mean lifetimes of specific transient species. (A) Mean lifetime of solvated electrons in tryptophan (solid circles), cutinase (solid triangles), and lysozyme (solid squares). (B) Mean lifetime of Trp· species at 330 nm in tryptophan (solid circles), cutinase (solid triangles), and lysozyme (solid squares). (C) Mean lifetime of Trp·+ at 560 nm (Trp sample, solid circles), and of Trp· species at 510 nm (Lys sample, solid squares).
