| Research Abstract |
In this project, we have explored applications of sum-frequency generation (SFG) spectroscopy as a valuable probe for elucidating supra-functional systems with a special emphasis on vibrationally-electronically doubly resonant SFG (DR-SFG) process, which can provide detailed information on vibrational and electronic states of interface species. As the result of the project, we have developed various DR-SFG techniques, such as sensible and selective detection of aromatic groups in organic monolayers by IR-UV DR-SFG spectroscopy, sensitive detection of chirality of very thin molecular films by DR-SFG, and a new methodology for detecting fingerprint region vibrational SFG spectra of silanized monolayer-aqueous solution interfaces.
