Using ultraviolet photoelectron spectroscopy (UPS), we have identified the first four highest occupied molecular orbitals (HOMO) of methanol adsorbed on rutile TiO2(110) for the first time. Showing the mismatch of the static energy level, we have discussed the possibility of investigating the transient electronic structure, level alignment and charge transfer in the prototypical methanol/TiO2 photocatalytic system with high harmonic generation (HHG) based time- & angle-resolved photoemission spectroscopy (TR-ARPES).
