dc.description.abstractWe will present results of an ab-initio MCSCF/CI study of the curve crossing region for linear $KBr_{2}$. The calculations were performed with effective core $potentials^{1}$ for both Br and $K^{2}$ and a valence double zeta plus polarization basis set. A single set of MCSCF orbitals was used to perform the Cl; the configuration list included up to quadruple excitations from a multireference set. The distance between K and the center of mass of $Br_{2}$ was fixed at 15 a. u. which places the system in the region where a vibrational barrier has been postulated. The barrier has been found in a DIM $calculation^{3}$. We have also calculated coupling matrix elements between the diabatic ionic and covalent states. We shall report energies and matrix elements and compare them with estimates obtained from semiempirical $models^{3,4}$.en_US
