Abstract
We have recorded a vibration–rotation spectrum of 28SiH4 from 840 to 1040 cm−1 with a Fourier transform spectrometer operating with an apparatus-function width of 2 × 10−3 cm−1. An analysis of microwave transitions and 919 combination differences between two different ground state levels and an excited level belonging to the band ν2 or ν4 have been used to determine the value of the ground state constants as expressed in a sixth-order Hamiltonian development. The experimental spectrum needed was recorded with the Fourier transform spectrometer of the Laboratoire de Spectronomie Moléculaire de Paris. The experimental precision is about 0.0001 cm−1. The calculation reproduces these 919 differences with a standard deviation of 0.00019 cm−1.
