ExoMol XVI: The hot line list for H2S AYT2 (updated on 18.09.2022) =============================================================================== Description: The data are in two parts. The first, H2S_AYT2.dat contains a list of rovibrational states. Each state is labelled with 3 vibrational (v1, v2, v3) and 3 rotational (J, Ka, Kc) quantum numbers and total symmetry. An additional column indicates the source of the quantum numbers, empirical (e) or calculated (c). "NaN" indicates that the quantum numbers are not available. The total degeneracy is given to facilitate the intensity calculations and the lifetmes (s) are given in the column 5. Because of their size, the transitions are listed in 20 separate files, each containing all the transitions in a 1000 cm-1 frequency range. These and their contents are ordered by increasing frequency. The name of the file includes the lowest frequency in the range; thus the a_05000.dat file contains all the transitions in the frequency range 5000-6000 cm-1 but not including 6000 cm-1. The transition files a_xxxxx.dat contain three columns: the reference number in the energy file of the upper state, that of the lower state and the Einstein A coefficient of the transition. The energy file and the transitions files are bzipped, and need to be extracted before use.
