X-ray emission spectra in stoichiometrically highpurity Ba1-xSrxTiO3 (X = 0 to 1) powder have been investigated because of the poor understanding of the physics of electronic structure in such systems. The Sr Kbeta emission band was found to contain two bands around 15.88 and 16.15 keV attributed to Kbeta1 and Kbeta3 respectively. The Ti Kbeta emission spectra were found to shift towards low energy side with the increase in Sr concentration. The binding energy (BE) of L level remains unchanged with the Sr concentration. From these observations it has been possible to conclude that change in the stoichiometry of the compound does not change the process of multiple ionisation or core hole-electron interaction. Further for Ti Kbeta emission, it has been possible to say that 4p states of Ti hybridises with 2p states of oxygen and this hybridisation decreases with the increase in vacancies in the system. This results in pushing up the Fermi level E(f).
