First measurements of line intensities for ν 1 and ν 3 bands of D 2 32 S are reported. About 300 intensities of D 2 32 S vibration–rotation lines were obtained from experimental high-resolution spectra recorded in the 1810–2051 cm −1 region with the Fourier Transform Spectrometer built in Reims. Empirical values of transition moment parameters for ν 1 and ν 3 bands of D 2 32 S were determined for the first time using a least-square fit to the observed intensities. Experimental D 2 32 S intensities were compared with recent global variational predictions [Vl.G. Tyuterev, L. Regalia-Jarlot, D.W. Schwenke, S.A. Tashkun, Y.G. Borkov, C. R. Phys. 5 (2004) 189–199] computed from isotopically invariant potential and dipole moment functions of the hydrogen sulphide molecule. Average discrepancy between these calculations and our observed data was 0.03 cm −1 for line positions of this spectral range. The discrepancy between these calculations and our measurements for the sum of line intensities was 5.5% and 3.5% for the ν 1 and ν 3 bands, correspondingly. |
