Estimate of the inversion barrier in SbH3

Abstract
Ab initio self‐consistent field calculations have been performed on the planar and pyramidal forms of SbH3. A slater orbital basis set Sb(1s,2s,3s,4s,4s′, 4s,2p,3p,4p′, 4p, 3d,3d′, 4d,4d′,4d) and H(1s2s2p) was employed, and the calculated barrier is 46.2 kcal/mole. A discussion of the use of split valence Slater orbital basis sets is also present.
