Abstract
The rotation-bending-torsion Hamiltonian (M. Krȩglewski, J. Mol. Spectrosc., in press) is used to simultaneously fit observed rotational transitions (J. A. Duckett, Ph.D. thesis, University of Reading, 1976) of silyl isocyanate SiH 3NCO in 18 vibrational states involving excited quanta of the ν 10 SiNC skeletal bending mode. The effective SiNC bending potential energy function and the geometry of the molecule in the small amplitude vibrational ground state are determined from the microwave data.
