DYNAMICS OF DANGLING OD-STRETCH AT THE AIR/WATER INTERFACE BY HETERODYNE-DETECTED SFG SPECTROSCOPY
MetadataShow full item record
Publisher:Ohio State University
SFG spectra of dangling OD-stretch at the air/water interface contain information on vibrational dephasing dynamics, ultrafast reorientational molecular motion, and vibrational energy transfer. To better separate these processes we conducted heterodyne-detected SFG experiments to measure real and imaginary contributions of the SFG spectrum of the dangling OD-stretch at the air/D$_2$O interface for SSP, PPP, and SPS polarizations. Variations in the temporal profiles of the SFG signals for these three polarizations will be also discussed.
