| Research Abstract |
We have extended heterodyne-detected vibrational sum-frequency generation(HD-VSFG) spectroscopy to time-resolved measurements. In this measurement, we first irradiate an infrared pump pulse to vibrationally excite the molecules and then performed a HD-VSFG measurement after an adequate delay time to trace the ultrafast vibrational dynamics through the temporal change of the imaginary part of the second order nonlinear susceptibility. We applied this newly-developed time-resolved HD-VSFG spectroscopy to charged water interfaces, and succeeded in measuring femtosecond time-resolved vibrationalχ^<(2)> spectra of liquid interfaces for the first time.
