Abstract
Temperature-dependent and photoinduced x-ray absorption spectra were measured in the Ti- edge of . The change in the spectra is explained by a collapse of the inversion symmetry, accompanied by a relative local vibration of the Ti atom. In particular, photoinduced x-ray absorption measurements show that the single axial vibration of the Ti atom along the Ti-O direction was excited by UV irradiation only in the quantum paraelectric phase.
