High‐quality SCF‐MO calculations yield a barrier to internal rotation of 1.70 kJ mole −1 for Ge 2 H 6 . A new contraction scheme is reported for Dunning's larger Ge basis set. Geometry optimization, although carried out, is unimportant in this particular calculation. Wavefunctions and properties are reported for GeH 4 and the staggered and eclipsed conformers of Ge 2 H 6 . The magnitude of the calculated barrier is more physically reasonable than those deduced from experimental data. Comparisons are made across the two series X 2 H 6 and CH 3 XH 3 .
