Abstract

Monoisotopic stannane ¹¹⁶SnH₄ has been investigated at room temperature in the 600–850 cm^-1 and 1270–1600 cm^-1 regions by FTIR spectroscopy with an effective resolution of  cm^-1 and  cm^-1 respectively. The simultaneous analysis of infrared transitions of both the bending triad and the hot band {bending triad} minus {bending dyad}, enabled us to determine 26 parameters for the (2 band and the combination band (. The standard deviation of the fit was about  cm^-1. In this analysis, we have used, for the bending triad, a Hamiltonian developed to the fourth order of approximation. 163 observed transitions for the hot band and most observed transitions for the bending triad spectrum, were assigned to the two bands 2 and (, up to J=9. In the fit of the Hamiltonian parameters, we have used for the ground state and for the fundamentals and , the parameters determined by Brunet, Pierre, and Bürger [J. Mol. Spectrosc. 140, 237 (1990)].
