Abstract: The carrier doping dependence of electronic structure is investigated by means of heat capacity and V NMR measurements in titanium and vanadium oxide compounds. The effective electron masses are enhanced near the metal-insulator transition boundary in Ca1−xYxVO3 and Sr1−xLaxTiO3, indicating a s ignificant increase in electron correlations with carrier filling. The hyperfine field of 51V is found to be 246 kOe in the magnetically ordered state of YVO3. The nuclear spin-lattice relaxation rate of 51V in Ca1−xVYxO3 at least for x
