A vibrationally adiabatic model is used to predict the positions of resonances in reactive scattering for collinear H + H/sub 2/, H + FH, and Cl + H/sub 2/ and isotopic analogues of these reactions and for three-dimensional H + H/sub 2/. Good agreement was obtained with accurate quantum mechanical results for both shape and Feshbach resonances. In some cases the agreement is better if it is assumed that the system follows a dynamical path on which the internal centrifugal forces are balanced by the potential energy surface than if it is assumed that the system follows the minimum-energy path.
