Correlation functions for polyproline-AF488-Atto 740: G_GG(τ) (green squares), G_RR(τ) (red circles), G_GR(τ) (green triangles), and G_RG(τ) (blue inverted triangles). The solid lines show a global fit where the transit times for G_GG(τ), G_GR(τ), and G_RG(τ) were linked (see text) and the initial amplitudes were allowed to vary independently. Fitting parameters are in Table 1.
