| Outline of Final Research Achievements |
Because interfaces play crucial roles in many phenomena that are important in a wide range of science and technology, molecular-level understanding of interfaces is highly desired. In this study, we developed new interface-selective time-resolved nonlinear vibrational spectroscopic methods, by combining the femtosecond photoexcitation and multiplex heterodyne-detected vibrational sum-frequency generation technique developed by us. Using the newly developed methods, we succeeded in tracing femtosecond-picosecond dynamics at water interfaces, including the observation of hole-burning indicating inhomogeneity of hydrogen bonds of interfacial water as well as the following spectral diffusion that occurs on the time scale of a few hundred femtoseconds.
