Abstract

Sulfur $K$ - and titanium $L_{2, 3}$ -edge absorption spectra of transition-metal disulfide, Ti $S_{2}$ , were measured using x-ray-absorption spectroscopy (XAS) and electron-energy-loss spectroscopy (EELS), respectively. All features in the experimental spectra are very well reproduced by full multiple-scattering-theory calculations. Combined analysis of theoretical and experimental XAS and EELS spectra, and linear muffin-tin orbital band-structure calculations, tend to demonstrate that Ti $S_{2}$ is a semimetal.
