Spectra of the rare gas hydrides V: The np Rydberg series of KrD

Abstract

The 23 920 cm^-1, 21 950 cm^-1, and 17 840 cm^-1 emission bands of KrD have been analysed successfully as transitions from the 8p, 7p, and 6p Rydberg complexes to the lowest bound state, ²Σ. It was found that the structure of these states corresponds to a special case of l uncoupling with a Coriolis-like linear dependence of the case (d) electron-rotation energies on the quantum number R. The structure of the lowest member of the series, the 5p(²Σ, ²Π) complex, has been obtained from the simultaneous analysis of the 5 050 cm^-1 and 5 800 cm^-1 emission bands as transitions from the 4d²Π case (b) upper state to the 5p²Σ and 5p²Π components of the complex. The latter are widely split, E _Π - E _Σ = 735 cm^-1, due to electronic interactions and are further distorted by strong spin-orbit interactions. The 5p(²Σ, ²Π) complex corresponds to the p complex of ArD studied recently by Dabrowski, I., Dilonardo, G., Herzberg, G., Johns, J. W. C., Sadowskii, D. A., and Vervloet, M., 1992, J. chem. Phys., 97, 7093.
