The electronic structure of the layered compound 1T-, before and after deposition of , was studied by angle-resolved photoelectron spectroscopy. 4p core-level spectra were found to consist of two spin-orbit doublets, of which one could be unambiguously attributed to intercalated . Valence band spectra, which were compared with band structure calculations, provided further support that was intercalated, in conflict with recent claims. Possible explanations of the conflicting results are discussed.
