Abstract : We have measured the absorption at Ti K edge, V K edge and Ta L edge in Ti,VO2 , Ti,NbO2 and Ti,TaO2 solid solutions. Comparison of the edge spectra of these compounds shows evidence of a partial charge transfer between Ti and Nb and variations of the ligand field and the size of the coordination octahedron. Lastly, we have detected the presence of an excitonic peak at Ti or V edge in all solid solutions.
