Spin-orbit all-electron configuration interaction study on the electronic structure and radiative lifetimes of low-lying excited states of CdH

We calculated the potential energy curves of 10 Lambda-S states correlated with the five lowest dissociation limits of the CdH radical by a configuration interaction method, as well as those of 17 Omega states generated from the Lambda-S states. The spectroscopic parameters of bound states were calculated and found to be well consistent with the latest experimental results. We also discussed the possible predissociation mechanisms of C-2 Sigma(+), 4(2)Sigma(+) and 2(2)Pi states on the basis of the calculation of spin-orbit elements. Finally, the allowed transition dipole moments and the radiative lifetimes of A(2)Pi, B-2 Sigma(+) and C-2 Sigma(+) states were obtained. (C) 2014 Elsevier B. V. All rights reserved.
