a-c) Selected time-resolved emission spectra for Q322C-BD (a), S596C-BD (b), and GS-BD (c) in 0.1 M borate pH 9.0 at 30 °C. d-f) Temperature dependence of Stokes shift decay rates for Q322C-BD (d), S596C-BD (e), and GS-BD (f) normalized in terms of solvation correlation function C(t). Decays are shown at 10 – 40 °C and were fit to either a bi-exponential (for Q322C-BD and S596C-BD) or a single exponential (for GS-BD) decay function. g-h) Arrhenius plots of 1/τ2 for Q322C-BD and S596C-BD (g), and 1/τ for GS-BD (h).
