| Résumé : | The absorption and the emission spectra of the BeH and BeD molecules in the region of 1850 Å are rotationally analysed. The features observed are shown to correspond to a transition between thèZ+ ground state and a 3d molecular complex that is strongly predissociated by thè C2Z+ state. Rotational constants for the v = 0 and v = 1 levels of the 3d state are derived by matrix X2Σ+diagonalization techniques, assuming interaction with the F(4pσ)2Σ+state. A tentative assignaient of previously observed absorption bands to transitions involving the v = 2 level of the 3d state is given. The 2-0 band of the B2∏-X2Σ++ transition of BeH and BeD is also identified in this region. The predissociation by the C2Σ+state is discussed. © 1991 Taylor & Francis Ltd. |
