 Title: CI STUDY OF THE WATER DIMER POTENTIAL SURFACE Creators: Matsuoka, O.; Yoshimine, M.; Clementi, E. Issue Date: 1975 Publisher: Ohio State University Abstract: Potential energies of the water dimer in various geometrical configurations have been calculated with a configuration-interaction method. The potential minima for the linear, cyclic, and bifurcated water dimers are found to be $-5.6(-1.1)$, $-4.9(-1, 2)$, and $-4.2(-0.9)$ kcal/mole, respectively (quantities in parentheses are the correlation effects). The cyclic dimer is found to have the shortest equilibrium 0-0 distance, 2.87 {\AA}, followed by 2.98 {\AA} for the linear and 3.01 {\AA} for the bifurcated. The computational method used and analysis of the correlation effects on the dimer potential in terms of the inter- and intra-molecular contributions will also be presented and discussed.
