Potentials energy surfaces for $Ar-H_{2}$ obtained from ab initio calculations have been proposed $recently,^{2-3}$ but they have not been tested directly against those data. Although $Ar-H_{2}$ is one of the simplest Van der Waals complexes, it is one of the first systems for which fully dimensional ab initio potentials are available, so this provides a unique opportunity to assess quantitatively the accuracy of intermolecular potentials which are obtained ab initio. We have used these theoretical potential energy surfaces for $Ar-H_{2}$ to calculate infrared and microwave transition frequencies for comparison with experiment. The results of these calculations will be presented and discussed. en_US dc.format.extent 75051 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title A COMPARISON OF EMPIRICAL AND AB INITIO POTENTIAL ENERGY SURFACES FOR $Ar-H_{2}$ Carey Bissonnette. en_US dc.type article en_US
