  OH-bond reorientation in water over short to intermediate timescales



Time: 1:20pm, December 31 (Thursday)

Title: OH-bond reorientation in water over short to intermediate timescales

Speaker: Prof. Ten-Ming Wu
   (Institute of Physics, National Chiao-Tung University)

Place: Science Building III B1 SC157


Water molecules reorient in many physical processes and biological systems.
In recent years, OH-bond reorientation in water has been explored by using ultrafast spectroscopy.
In this talk, the 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.
