Abstract
The Wall-Porter method of rotating a Morse function to construct potential energy surfaces for collinear atom-diatom chemical reactions is modified by using a numerical spline interpolation technique. This procedure is shown to have great flexibility in giving a potential surface desired characteristics, such as the saddle-point location and the barrier height and curvature at this point, for either symmetrical or unsymmetrical reactions. Extensions of the method to non-reactive and non-collinear potential surfaces are also discussed.
