We have performed a systematic tight-binding analysis of the angle-resolved photoemission spectroscopy (ARPES) spectra of a series of transition-metal (TM) oxides A(TM)O 3 and compared the obtained electronic structure parameters with those well established values obtained from cluster-model analyses of photoemission spectra. The values of ε d -ε p from ARPES are found to be much larger than the values which would be expected for the limit of weak p – d hybridization, indicating that the “effective” TM 3 d bands are originated from the strong hybridization with the O 2 p bands even for light TM oxides.
