Abstract
A large configuration‐interaction calculation has been performed to determine the wave function, energy, and molecular properties of CO. The most important configurations were used to obtain the natural geminals and their occupation numbers. A pair‐energy approach to the correlation energy was attempted with results which differ significantly from the configuration‐interaction results.

It is possible to calculate the ground-state wave function and energy of a periodic solid by applying quantum chemical methods. The accuracy achieved is comparable with that for small molecules. The many-body problem of the correlated ground state is expressed in terms of cumulant scattering matrice
