Method Current interpretations of Raman-induced Kerr effect [G,E. Walrafen, M.R. Fisher, M,S. Hokmabadi and W-H Yang. J. Chem. Phys. 85 (1986) 6970], Rayleigh light scattering [CJ. Montrose, J,A, Bucaro, J, Marshall-Coakley and TA, Litovitz, J, Chem Phys, 60 (1974) 5025] and inelastic neutron scattering [M,-C Bellissent-Funel and J, Teixeira, J, Mol. Struct. 250 (1991) 213] suggest above range.
Comments Proton hopping times as obtained by NMR and 17O resonance (S. Meiboom, J. Chem. Phys. 34 (1961) 375) are of similar magnitude, tP˜1.5ps.
