The band structures of the perovskite oxides LaTiO{sub 3} and LaNiO{sub 3} are reported here. The band structures were done using the linear muffin tin orbital (LMTO) method. The Fermi energy, density of states at the Fermi energy and the number of electrons in the conduction band were all determined. These quantities were used to calculate the electronic specific heat coefficient and the Pauli paramagnetic susceptibility. The Stoner parameter with regard to the enhancement in the Pauli susceptibility is calculated in the Thomas-Fermi approximation and is compared with the {chi}{sub expt}/{chi}{sub bs} value.
