Abstrakt: We present a method to ensure the sign consistency of dynamical couplings between ab initio three-center wave functions. The method also allows to systematically “diabatize” avoided crossings between two potential energy surfaces, including conical intersections. Illustrations are presented for H3+, LiH2+, and NH25+ quasimolecules.© 2004 American Institute of Physics. [ABSTRACT FROM AUTHOR]
