Abstract

The high resolution infrared spectra of SiD4 were recorded with Bruker IFS120 and IFS125 HR Fourier transform infrared spectrometers at an optical resolution of 0.002 and 0.0021 cm−1 and analyzed in the region of 1480–1700 cm−1 where the stretching bands ν3 and ν1 are located. The 2676 transitions with Jmax. = 44 were assigned to the ν3 band.The subsequent weighted fit of experimentally assigned transitions was made with the Hamiltonian model which takes the resonance interactions between the (0010) and (1000) vibrational states into account. As the result, a set of 18 fitted parameters was obtained which reproduces the initial 2676 ro–vibrational transitions with the drms=3.71×10−4 cm−1.
