(a) Normalized static Ti K-edge XANES spectrum of colloidal nanoparticles of anatase TiO2 at room temperature. (b) Transient (difference) Ti K-edge XANES spectra (difference of the excited minus the unexcited sample absorption) for 355 nm excitation of colloidal nanoparticles of anatase TiO2, recorded at time delays of 100 ps (green squares, left vertical axis)16 and 1 ps (this work, blue dots, right vertical axis).
