Title: A preliminary prediction of the (ν{sub 2} + ν{sub 4}) combination band of {sup 34}SF{sub 6}

Abstract

Sulfur hexafluoride appears to be a species of growing importance in the field of atmospheric physics and chemistry as a pollutant that can contribute to the greenhouse effect. The infrared spectroscopy of SF6 is essential for quantitative measurements in the atmosphere, is still insufficiently known. In this work, we present a new contribution to this topic concerning (ν{sub 2}+ν{sub 4}) combination band. The prediction of this band is based on the tensorial formalism and vibrational extrapolation methods developed in Dijon. The effective Hamiltonian contains contribution from the ground state level GS, ν{sub 2} and ν{sub 4} witch are known from previous studies. The analysis has been performed using nonlinear least squares fit procedure included in the XTDS program to Jup=95.
