The Result shows that the first ionization condition and the bottom affinity condition have significant O 2p character due to the big hopping matrix element between Ti (V) 3d and O 2p orbitals. In par... We now have calculated experimentally and analyzed theoretically the Ti 2p X-ray photoemission spectra (XPS) https://socialeweb.com/story3973145/the-definitive-guide-to-okada-4d
