Book Synopsis Spectroscopic Investigations of Hydrogen Bond Dynamics in Liquid Water by : Christopher J. Fecko
Book excerpt: (Cont.) At short times, vibrational dephasing reflects an underdamped 180 fs hydrogen bond oscillation, but the long time behavior indicates collective structural reorganization of the hydrogen bond network a 1.4 ps timescale. The anisotropy decays on timescales of 50 fs and 3 ps, which are attributed to librations and rotational diffusion, respectively. Lastly, I used two-dimensional infrared spectroscopy to investigate the frequency dependence of the dynamics. Preliminary results reflect a distribution of timescales for both local motion and collective reorganization.
