An analysis of a superweak absorption spectrum of the SO<sub>2</sub> molecule using the variational procedure

Abstract

The high resolution structure of a superweak 2ν₁+ν₂+ν₃-ν₂ band of sulfur dioxide, SO₂, is for the first time recorded with a Bruker IFS-120 HR Fourier spectrometer and analyzed using a specially derived procedure and a relevant computer code. As a result of the analysis, 115 lines have been found in the recorded spectrum, which allowed us to obtain high-accuracy values of the vibrational energy and rotational parameters of the highly excited vibrational state, (211).
