Both the Ti Kβ 5 and Ti Lα X-ray emission spectra of metallic titanium and its hydrides TiH 1.88 , TiH 2.27 , and TiH 2.52 have been investigated. In the above spectra the differences of energy distributions of Ti p-like and Ti d-like valence states of the hydrides have been observed. The observed peculiarities of interatomic interactions have been explained taking into account that, in the hydrides TiH x>2 , hydrogen atoms begin to occupy octahedral positions in addition to tetrahedral ones. The X-ray Ti K absorption spectra of Ti met , TiO 2 and the hydrides mentioned above have also been studied. Results of investigations of the Ti K absorption spectra indicate that, in the titanium hydrides studied, a charge transfer occurs from Ti to H atoms.
