(B) Binary oxide systems: (i) Cr2O3-Al2O3, (ii) Cr2O3-Fe2O3, (iii) Cr2O3-ZnO, (iv) Al2O3-SiO2, (v) Al2O3-Fe2O3, (vi) MnO-Cr2O3, (vii) Cu-Al2O3, (viii) ZrO2-Cr2O3, (ix) NiO-Cr2O3, (x) ZrO2-NiO, (xi) ThO2-Al2O3.

    Recursion formulae for calculation of overlap integrals (1987)

    Notes: Multi-ζ Slater-type orbitals are frequently used in molecular orbital calculations. Master formulae and numerical tables are available in literature for overlap integrals between s, p, and d atomic orbitals up to principal quantum number (n) = 3 and for some other selected quantum numbers. However, no master formula or numerical table is available for quantum numbers n = 5 and above and involving ƒ orbitals. In this article recursion formulae have been presented for the calculation of the overlap integral between any two s, p, d, and ƒ atomic orbitals formed by a linear combination of Slater-type orbitals. These formulae, when expanded, would give rise to all the master formulae reported in the literature as well as formulae hitherto unreported.
