A detailed high-accuracy list of the SO2 molecule absorption lines was obtained in the 2000-3000 cm-1 spectral region, which is important for atmospheric applications, based on a combination of the high-accuracy data on experimental energy levels and variational calculations of the intensities of vibrational-rotational transitions. The expert list contains 70565 absorption lines with an intensity cut-off 1.0E-27 cm/molecule. The results obtained are compared with published data.
