Abstract: Water molecules reorient in many physical processes and biological systems. In recent years, OH-bond reorientation in water has been explored with ultrafast spectroscopy. In this talk, OH-bond orientational relaxation in water was investigated over short to intermediate timescales, within which molecules undergo inertial rotation and libration and then enter the rotational diffusion regime [1]. The simulated molecules were classified into subensembles, according to either their local structures or H-bond configurations. Through the OH-bond orientational time correlation functions, the local-structure effects on OH-bond reorientation in water were examined and discussed.
