Abstract
A review of the coupled Hartree-Fock method for calculation of second-order one-electron properties is given with special reference to force constants and static electric and magnetic properties. A comprehensive analysis of the computational problems is attempted and we present the logic of a computer programme. A number of results obtained for the H2O molecule are reported in part II of this work.
