High-resolution K{beta} x-ray spectra induced by 2 MeV protons in thick Ti, TiO, Ti{sub 2}O{sub 3}, TiO{sub 2}, MgTiO{sub 3}, FeTiO{sub 3}, TiC, TiN, and TiB{sub 2} targets were measured using a wavelength dispersive spectrometer combined with a position-sensitive detector. The intensities and energies of the K{beta}{sub 2,5} and K{beta}{sup ''} lines relative to the K{beta}{sub 1,3} line were extracted. The influence of self-absorption in thick targets was investigated using related x-ray-absorption near-edge-structure spectra that are available in the literature to extract mass absorption coefficients close to the K absorption edge. The correlation of the relative position of the K{beta}{sub 2,5} line with a titanium formal oxidation state in oxide compounds confirmed that the oxidation state of Ti in FeTiO{sub 3} is probably a mixture of Ti III and Ti IV states, which has been recently reported by other authors using different methods. The strengths of the K{beta}{sub 2,5} and K{beta}{sup ''} transition probabilities per titanium-ligand pair were found to decrease exponentially as the average titanium-ligand bond distance increased, which is similar to results obtained for various compounds with vanadium or manganese as the central 3d metal atoms.
