An analysis of the dipole polarizabilities, cohesive energies, and pressure derivatives of bulk moduli of some rutile‐type oxide crystals is presented. Two interionic potentials, within the framework of the ionic model, are considered and the results obtained are compared with available experimental data and other recent theoretical calculations. A discussion of the controversy over the bonding character of these compounds is included. The suitability of a new interionic potential due to Islam as applied to these systems is also shown.
