Abstract

The FTIR spectrum of monoisotopic stannane ¹¹⁶SnH₄ has been recorded in the 600–850 cm^-1 range, with the Bruker 120 HR interferometer at Giessen, Germany. The resolution was  cm^-1. The analysis of infrared transitions in this region enabled Brunet et al. [CITE] to assign many lines to the bending dyad . However, several lines in this spectrum were found to be unassigned. In a recent work [CITE], we have analysed the infrared spectrum of stannane in the bending triad region at 1400 cm^-1. The results obtained enabled us to assign directly, for the spectrum in the region 600–850 cm^-1, 163 of the observed transitions to the hot band {bending triad} minus {bending dyad} up to J=9. These transitions were combined to the infrared data corresponding to the bending triad (), to refine a set of Hamiltonian parameters for the two bands and () [CITE].
