Abstract:
Accurate line lists are calculated for aluminium monoxide covering the
pure rotation, rotation-vibration and electronic (B-X blue-green and
A-X infrared bands) spectrum. Line lists are presented for the four
isotopologues of AlO. These line lists are suitable for high
temperatures (up to 8000K) including those relevant to exoplanetary
atmospheres and cool stars. A combination of empirical and ab initio
methods is used: the potential energy curves were previously
determined to high accuracy by fitting to extensive data from analysis
of laboratory spectra; a high quality ab initio dipole moment curve is
calculated using quadruple zeta basis set and the multi-reference
configuration interaction (MRCI) method. Partition functions plus full
line lists of transitions are made available in an electronic form as
supplementary data to this article and at www.exomol.com.
Description:
The data for each isotopologue are in two parts. The first, .states
contains a list 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 transition files 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.
A sample programme to generate synthetic spectra from the ExoMol
format line lists can be obtained at www.exomol.com.
