A. Metropoulos, GENERATION OF DIATOMIC DIABATIC STATES BY A GENERAL MULTISTATE ROTATION, Zeitschrift fur Naturforschung. A, A journal of physical sciences, 48(4), 1993, pp. 577-580
We present a general multi-state orthogonal transformation program tha
t generates a set of diatomic electronic diabatic states from a set of
vibronically interacting adiabatic states of the same symmetry.
