Abstract
Polarization-selective pump-probe and echo experiments on the OH vibration of HOD in with (fs) infrared pulses are analyzed self-consistently to reveal the time scales for vibrational relaxation, dephasing, and molecular reorientation. Librational motion and hydrogen bond fluctuations on 50- and time scales precede picosecond collective reorganization.
