Franck – Condon Factors And r- Centroids of D – A and D – B band systems of AlO molecule

Abstract

Franck–Condon factors and r-centroids were computed for the D2S+ - A2Πi and D2S+ - B2S+ band systems of the aluminium oxide (AlO) molecule for the v' = 10; v" = 10 matrix using the method developed by Jarmain and Nicholls. The latest Fourier-transform Spectrometer molecular constants of ground and excited state are used. The intensities of these bands are discussed and the Franck–Condon factors and r-centroids obey the established relationships
