Measurements of line intensities and determination of transition moment parameters from experimental data for the ν1 and ν3 bands of D232S

First measurements of line intensities for ν1 and ν3 bands of D232S are reported. About 300 intensities of D232S 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 ν1 and ν3 bands of D232S were determined for the first time using a least-square fit to the observed intensities. Experimental D232S intensities were compared with recent global variational predictions [Vl.G. Tyuterev, L. Régalia-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 ν1 and ν3 bands, correspondingly.
