are investigated. The main results are given in the form of tables from which the exact wave functions can be obtained. A set of figures showing the behaviour in going from the united atom limit to the separated atoms limit is also presented. The 2
pσ
state is bound; for it the equilibrium internuclear separation is 2∙05
9
Å and the dissociation energy is 0∙849

eV.
