Abstract
The band spectrum of BaO has been obtained by spraying barium chloride solution into a flame. The integrated intensities of the bands have been determined by photographic photometry. The experimental results along with the theoretically computed Franck-Condon factors have been used to evaluate a relation between Re, the electronic transition moment, and r, the internuclear separation, in the form Re(macronrνprimeνPrime) = constant (1 - 0536r). This relation has been used to obtain improved Franck-Condon factors. The theoretically computed Franck-Condon factors, with and without the inclusion of Re variation, have been compared with the experimental band strengths.
