| contents | An analysis of the measured rovibrational transitions is carried out for the 12C32S2 isotopologue of carbon disulfide. Data from 21 sources is extracted and validated using a consistent set of standard linear molecule quantum numbers. A corrected list of 8714 CS2 transitions forms the input to a Measured Active Rotational-Vibrational Energy Levels (MARVEL) procedure, generating 4279 empirical rovibrational energy levels across 138 bands of 12C32S2. Results are compared to the recent NASA Ames line list. While the agreement is generally good, issues are identified with the energy levels of some states, notably those with high values of the v2 bending quantum number. |
