Abstract

This work communicates line strength data and associated scripts for computation and spectroscopic fitting of selected transitions of the diatomic molecules AlO, C2, CN, OH, N2+, NO, and TiO. For ease of use, the scripts for data analysis are designed for inclusion in various software packages or program languages. The accuracy of the data is of the order of less than one picometer, suitable for analysis of laser-induced fluorescence and laser-plasma spectra. Selected results demonstrate the applicability of the program for data analysis in laser-induced optical breakdown spectroscopy primarily at The University of Tennessee Space Institute, Center for Laser Applications. Representative spectra are calculated and referenced to measured data records.

Comment: Edited various sections, provided more detail on refractive index, edited the MATLAB scripts, included comments regarding other databases, provided a comparison with OH ExoMol data, included extra references, and updated supplement-file.

(Hopefully this correction can be used as version2 preprint of the paper.)
