Title: Room temperature line lists for CO\2 symmetric isotopologues with \textit{ab initio} computed intensities,
Abstract: Remote sensing experiments require high-accuracy, preferably sub-percent,
line intensities and in response to this need we present computed room
temperature line lists for six symmetric isotopologues of carbon dioxide:
$^{13}$C$^{16}$O$_2$, $^{14}$C$^{16}$O$_2$, $^{12}$C$^{17}$O$_2$,
$^{12}$C$^{18}$O$_2$, $^{13}$C$^{17}$O$_2$ and $^{13}$C$^{18}$O$_2$, covering
the range 0-8000 \cm. Our calculation scheme is based on variational nuclear
motion calculations and on a reliability analysis of the generated line
intensities. Rotation-vibration wavefunctions and energy levels are computed
using the DVR3D software suite and a high quality semi-empirical potential
energy surface (PES), followed by computation of intensities using an
\abinitio\ dipole moment surface (DMS). Four line lists are computed for each
isotopologue to quantify sensitivity to minor distortions of the PES/DMS.
Reliable lines are benchmarked against recent state-of-the-art measurements and
against the HITRAN2012 database, supporting the claim that the majority of line
intensities for strong bands are predicted with sub-percent accuracy. Accurate
line positions are generated using an effective Hamiltonian. We recommend the
use of these line lists for future remote sensing studies and their inclusion
in databases.
