The direct ab initio generation of potential energy surfaces for an elementary chemical reaction is discussed from the viewpoint of its use in dynamical calculations within the hypenpherical coordinate framework. An example is given of the reaction 0( 'P ) + H2 +OH + H, for which kinetic paths (vall
Using MCSF and CIPSI3 methods the shape of the potential energy surface (PES ) for the title reaction has been computed for the 'A' and 'A" states, locating the stationary points on each surface. The results from these two methods show that the wavefunction for all the stationary points has a strong
