Line Intensities for the v1, v3, and v1 + v3 Bands of 34SO2

Using both high resolution (0.0018 cm-1) and medium resolution ( 0.112 cm-1) Fourier transform spectra of an enriched 34S (95.3%) sample of sulfur dioxide it has been possible to accurately measure a large number of individual line intensities for some of the strongest of the SO2 bands, i.e. ν1, ν3 and ν1+ν3. . These intensities were least squares fitted using a theoretical model which takes into account the vibration-rotation interactions linking the upper energy levels where needed, and, in this way, expansions of the various transition moment operators were determined. The Hamiltonian parameters determined in previous analyses [Lafferty WJ, Flaud J.-M., Sams R.L., Ngom El H A.
