Abstract
A line list for two isotopologues of aluminium monochloride, AlCl35 and AlCl37 are presented covering the wavelength range <0.2 μm, J up to 400 and applicable for temperatures up to 5000 K. The line lists are built using an empirical spectroscopic model consisting of potential energy curves, spin-orbit coupling curves, electronic angular momentum curves and Born-Oppenheimer Breakdown correction curves combined with ab initio dipole moments and covers the four lowest electronic states, X 1Σ+, A 1Π, a 3Π and b 3Σ+. Considerable problems with the assignments of some the laboratory rovibronic spectra are identified. Treatment of the states lying in the continuum is discussed. The YNAT line list is available from the ExoMol database at www.exomol.com.
