Several dynamics studies have indicated that the product isotopic distributions and vibrational energy distributions in the reaction O(1D) + H2(HD) are very sensitive to the long range interaction of the reactants. In this paper, an improved calculation of the reactant region of the potential energy surface is reported. In agreement with previous work, no barrier is found to edge-on insertion (1 A-prime ground state water surface), but a smaller (less than 0.2 kcal/mol) barrier to collinear addition, 1 Sigma (+) surface, is found than in previous work. The long range potential obtained in the present work most closely resembles the SL3 surface.
