Vibrational transition probabilities of the bands of the barium oxide (A 1SIGMA-​X 1SIGMA) system

The band spectrum of BaO has been obtained by spraying BaCl2 soln. into a flame. The integrated intensities of the bands have been detd. by photographic photometry. The exptl. 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 sepn., in the form, Re(r v'v'') = const.(1 - 0.536r)​. 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 exptl. band strengths

Vibrational transition probabilities of the bands of the boron oxide [BO]​-​α system

Franck Condon factors have been computed for the BO mol. by using Bates' method. Together with available exptl. data they have been used to det. the relation between the electronic transition moment, Re, and the internuclear sepn., r: Re(r) = const. (1-​0.4584 r)​. With this relation better agreement with theoretical values is obtained than previously

Excitation source - a note on the new design of a burner

A burner is described for exciting BaO band spectra, with min. interference from at. lines, by feeding the flame with aq. BaCl2. The burner, a single, rigid unit contg. a burner and atomizer, is based on the design of Lundegardh (1951)​, in which a liq. is atomized into the air supply of an air-​C2H2 flame, but uses petroleum gas

Study of the efficacy of Linnett's potential

For the mols. C2, BO, N2, BeO, MgO, CaF, and CN, the parameters of the model potential given by J. W. Linnett (1940) for diat. mols. were calcd. For BO, the calcd. potential-​energy curve agreed well with the true potential obtained by Singh and Rai (1985)​

Vibrational transition probabilities of the bands of the BaO (A 1Σ-x 1Σ) system

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 - 0centerdot536r). 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
