List of Molecules

  The following table lists the molecules presently in the line-by-line, traditional part of the HITRAN database, showing their assigned number in the HITRAN sequence along with their isotopologues (using the AFGL shorthand notation).
  Listed are the spectral extent and the number of transitions for each isotopologue. For comparison, the corresponding values from the previous HITRAN2008 database are also given in the table.

  The abundance values are based on P. De Bievre, N.E. Holden, and I.L. Barnes, “Isotopic Abundances and Atomic Weights of the Elements,” J.Phys.Chem.Ref.Data 13, 809-891 (1984).

  a Abbreviated AFGL code for isotopologues.
b Isotopologue 727 (17O12C17O) was introduced into HITRAN for the first time in the 2012 edition. Isotopologue 838, which existed in the database before but is of lesser terrestrial abundance, has been reassigned as the tenth isotopologue and has the number zero in the corresponding ASCII format transition field.
c Not included in HITRAN2008 and previous editions.
