^aValues were obtained via minimization of the χ² function defined by Eq. [14] together with Eq. [16] (Fitting Procedure 2 in Table 1). Values of the correlation times τ_c and τ_i were calculated to be 7.7 ± 0.8 ns and 0.21 ± 0.01 ns, respectively. The distribution radius RP, defined as a global parameter, was calculated to be 7.4 ± 0.6 Å.
