Abstract

Ti 2 p X-ray absorption spectra for a series of minerals have been measured. Crystal field multiplet calculations can explain the spectral shape. The asymmetry of the e_g, peak is shown to be related to distortions of the Ti^IV octahedron. It is found, theoretically as well as experimentally, that the absorption spectra are more sensitive to tetragonal distortions than to trigonal distortions. A number of silicate minerals and metamict minerals containing titanium are measured and Ti^IIIhas not been observed in any of these minerals. A comparison is made to the 1 s X-ray absorption, and the potential of both for the study of minerals is discussed.
