The electronic band structure and optical property calculationshelp usto find new photocatalysts with visible light response in theory. However, the appropriate band gap and band alignment sometimes do not mean better light absorption properties. With the help of detailed transition dipolemoment analysis, we can clearly reveal the catalytic mechanism of photocatalytic water splitting. In addition, our theoretical simulations show that the amplitude and phase of transition dipole moments play an importantrole in the at to second transient absorption spectra of atomic systems and thehigh-order harmonic spectra of crystal systems under ultrafast intense laser irradiation.
