摘要
Spectroscopic constants of the ground state of the As, molecule have been evaluated using a series of complete active space self-consistent-field and second-order configuration interaction calculations with all-electron basis jets. Angular correlation is found to contribute significantly to the dissociation energy. The calculation with a set of [8s6p3d2flg] basis functions gives 3.58 eV for the dissociation energy. in contrast to the experimental value of 3.99 eV. (C) 1997 Elsevier Science B.V.
