Abstract

The shift of vibrational frequency of surface OH groups on TiO₂ particles induced by UV pulse irradiation has been studied by time-resolved IR absorption spectroscopy. By the UV irradiation of the TiO₂ particles, the absorption intensity at 3696 cm^-1 was decreased and that at 3654 cm^-1 was increased. These changes were gradually recovered on a millisecond time scale. The transient changes were interpreted by a small (< 0.1 cm^-1) shift of a v(O-H) band at 3677 cm^-1. The temperature jump triggered by the UV pulse caused the shift.
