Abstract:

The high-resolution analysis of the ro-vibrational IR spectrum of the absorption bending bands ν₂ + ν₄ (F₁) and ν₂ + ν₄ (F₂) of the ²⁸SiH₄ molecule is performed with the SPHETOM software package. About 618 experimental transitions are assigned to ν₂ + ν₄ (F₁) and ν₂ + ν₄ (F₂) bands with J^max = 8. Rotational, centrifugal distortion, tetrahedral splitting, and resonance interaction parameters for these vibrational bands are determined from the weighted fit of experimental line positions. The obtained set of parameters reproduces the initial experimental data with the accuracy closed to experimental uncertainties, d_rms = 8 × 10^–4 cm^–1.

Keywords:

bending vibrations, overtones, tetrahedral splittings, resonance interactions
