 Title: DETERMINATION OF THE INTERMOLECULAR POTENTIAL OF $AR-H_{2}O$ FROM TUNABLE FAR INFRARED LASER SPECTROSCOPY Creators: Cohen, R. C.; Saykally, R. J. Issue Date: 1990 Abstract: The three-dimensional anisotropic intermolecular potential energy surface (PES) for argon interacting with a rigid $H_{2}O$ in its ground vibrational state has been determined by least squares fitting an analytical form for the PES to data obtained using tunable far infrared laser $spectroscopy. ^{1.2}$ We have extended a new numerical many-body method, the collocation $method,^{3}$ to three dimensions. This method provides a simple, efficient, and accurate route to calculation of the eigenvalues and eigenvectors of multidimensional systems. Comparison of the new AW1 potential determined in this work to previous approximate potentials will be presented. URI: http://hdl.handle.net/1811/18243 Other Identifiers: 1990-TA-3
