Abstract

This investigation elaborates on 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, B 2 Σ+ −→ X 2 Σ+, ∆v = 0, ±1, ±2, +3 sequences and progressions compare nicely with 1 nanometer resolution experimental results. The analysis discusses experiment data captured during laser ablation of Al2O3 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 AlO line strength and of ExoMol data for the 27Al16O diatomic molecule. Accurate AlO databases show a volley of applications in laboratory and astrophysical plasma diagnosis.
