  This work communicates analysis of aluminum monoxide, AlO, laser-plasma
emission records using line strength data and the ExoMol astrophysical
database. A nonlinear fitting program computes comparisons of measured and
simulated diatomic molecular spectra. Predicted cyanide spectra of the AlO,
${\rm B}\ ^2\,\Sigma^+ \longrightarrow {\rm X} \ ^2\,\Sigma^+$, $\Delta {\rm v}
= 0, \pm 1, \pm 2, + 3$ sequences and progressions compare nicely with 1
nanometer resolution experimental results. The analysis discusses experiment
data captured during laser ablation of Al$_2$O$_3$ with 266-nm, 6-mJ pulses.
The accuracy of the AlO line strength data is better than one picometer. This
work presents as well comparison of the $^{27}$Al$^{16}$O line strength and of
ExoMol data for spectral resolutions of 0.1 nm and 0.07 nm. Accurate AlO
databases show a volley of applications in laboratory and astrophysical plasma
diagnosis.
