Theoretical absorption spectrum of the Ar-CO van der Waals complex

Based on the results of a recent study where the rovibrational energy levels of the Ar-CO van der Waals complex were evaluated from a three-dimensional intermolecular potential energy surface obtained with the CCSD(T) method and the aug-cc-pVQZ-33211 basis set, the evaluation of the spectrum was continued by calculating the three-dimensional electrical dipole surface and from there the temperature-dependent spectral intensities. As such, the coupled cluster singles and doubles (CCSD) method and the aug-cc-pVTZ-33211 basis set was used for calculating the dipole surface.
