VizieR Online Data Catalog: ExoMol Line List XXI: Nitric Oxide (NO) (Wong+, 2017)
Abstract
The states files contain lists of rovibronic states. Each state is labelled with the total angular momentum, state degeneracy, total parity, vibrational quantum number, projection of the electronic, spin and total angular momenta. Each state has a unique number, which is the number of the row in which it appears in the file. This number is the means by which the state is related to the second part of the data system, the transitions files. The lifetimes and Lande-g factors are also provided.
The transition files t_*dat contain four columns: the reference number in the energy file of the upper state, that of the lower state, the Einstein A coefficient of the transition and the transition wavenumber. These entries are ordered by increasing frequency. The energy file and the transitions files are bzipped, and need to be extracted before use. The p_*.dat files contain the partition functions for the six isotopologues (0...5000K) tabulated in steps of 1K. The pf_param.dat contains unitless expansion parameters a_i of the partition functions extrapolated using the following form (Vidler & Tennyson, 2000, J. Chem. Phys., 113, 9766): log10(Q) = sumi ai [log10(T)]^i A sample programme to generate synthetic spectra from the ExoMol format line lists can be obtained at www.exomol.com. (19 data files).- Publication:
