Spectra of rare gas hydrides. VI. The 4f complex and the electronic structure of KrD

Abstract

The complete rotational analysis of the 4f(2Φ,2Δ,2Π,2Σ+)→4d 2Δ (6600 cm−1), 4f(2Φ,2Δ,2Π,2Σ+)→4d 2Π (8500 cm−1), and 4d 2Δ→5p 2Π (7100 cm−1) Rydberg electronic transitions of KrD is reported. The two newly observed states, the doublet 4f complex and 4d 2Δ together with the np(2Π,2Σ+), nd 2Σ+, ns 2Σ+, and nd 2Π studied earlier by Dabrowski et al., [Mol. Phys. 63, 269 (1988)], and by Dabrowski and Sadovskiı́ [Mol. Phys. 81, 291 (1994)], form a set of states which permits the whole Rydberg electronic structure of the molecule to be determined from the experimental data.
