Abstract
A new line list for AlH is produced. The WYLLoT line list spans two electronic states X 1+ and A 1. A diabatic model is used to model the shallow potential energy curve of the A 1 state, which has a strong pre-dissociative character with only two bound vibrational states. Both potential energy curves are empirical and were obtained by fitting to experimentally derived energies of the X 1+ and A 1 electronic states using the diatomic nuclear motion codes DPOTFIT and DUO. High-temperature line lists plus partition functions and lifetimes for three isotopologues 27AlH, 27AlD, and 26AlH were generated using ab initio dipole moments. The line lists cover both the X–X and A–X systems and are made available in electronic form at the CDS and EXOMOL data bases.
