Quantum-mechanical elucidation is made to the semiclassical theory in the dynamical-state representation previously proposed to deal analytically with the nonadiabatic rotationally induced transitions. A general path-integral formulation of the scattering matrix is given in terms of a product of two kinds of matrices. This enables us to treat a multistate curve-crossing problem involving both radial and rotational couplings. Discussions are made on the qualitative difference in collision-energy dependences of the ordinary Landau-Zener-type radial transitions and rotationally induced transitions.
