The electronic structure of double perovskite Pr2MnNiO6 is studied using corex-ray photoelectron spectroscopy and x-ray absorption spectroscopy. The 2px-ray absorption spectra show that Mn and Ni are in 2+ and 4+ statesrespectively. Using charge transfer multiplet analysis of Ni and Mn 2p XPSspectra, we find charge transfer energies {\Delta} of 3.5 and 2.5 eV for Ni andMn respectively. The ground state of Ni2+ and Mn4+ reveal a higher d electroncount of 8.21 and 3.38 respectively as compared to the atomic values of 8.00and 3.00 respectively thereby indicating the covalent nature of the system. TheO 1s edge absorption spectra reveal a band gap of 0.9 eV which is comparable tothe value obtained from first principle calculations for U-J >= 2 eV. Thedensity of states clearly reveal a strong p-d type charge transfer character ofthe system, with band gap proportional to average charge transfer energy ofNi2+ and Mn4+ ions.
