Marvel analysis of the measured high-resolution rovibrational spectra of H2S

44325 measured and assigned transitions of H$_2^{32}$S, the parent isotopologue of the hydrogen sulfide molecule, are collated from 33 publications into a single database and reviewed critically. Based on this information, rotation-vibration energy levels are determined for the ground electronic state using the Measured Active Rotational-Vibrational Energy Levels (MARVEL) technique. The ortho and para principal components of the measured spectroscopic network of H$_2^{32}$S are considered separately. The verified set of 25293 ortho- and 18778 para- H$_2^{32}$S transitions determine 3969 ortho and 3467 para energy levels. The Marvel results are compared with alternative data compilations, including a theoretical variational linelist.Comment: 39 pages, 3 figures, JQSRT, 201

Marvel analysis of the measured high-resolution rovibrational spectra of H₂³²S

Abstract 44 325 measured and assigned transitions of H₂³²S, the parent isotopologue of the hydrogen sulfide molecule, are collated from 33 publications into a single database and reviewed critically. Based on this information, rotation-vibration energy levels are determined for the ground electronic state using the Measured Active Rotational-Vibrational Energy Levels (Marvel) technique. The ortho and para principal components of the measured spectroscopic network of H₂³²S are considered separately. The verified set of 25 293 ortho-- and 18 778 para- H₂³²S transitions determine 3969 ortho and 3467 para energy levels. The Marvel results are compared with alternative data compilations, including a theoretical variational linelist
