FIGURE 5

The order parameter, Inline graphic (a) and time constant τif (b) of the fast (picosecond) internal motion. The data are from a fit using the two-contribution model, M2II (see text). The time constant τis of the slower internal motion was set to 2.5 ns in the fit. The order parameter of this internal motion, Inline graphic was found to be 0.75 ± 0.07 on average. The exact Inline graphic and τis values are given in Supplementary Material (Table S5).
