Abstract
A highly accurate and detailed expert list of absorption lines of the 32SO2 molecule in the range 0-4200 cm-1 has been created. The line centers in the expert list are determined from the experimental and calculated by the effective Hamiltonian energy levels, and the intensities are mainly variational data. The list contains 549200 vibrational-rotational transitions for 22 bands. The obtained centers and line intensities are compared in detail with the HITRAN2016 database and the AMES empirical list. Comparison with experimental data also shows that the accuracy of the variational calculation of the intensities of the spectral lines of the 32SO2 molecule depends on the vibrational quantum numbers.
