For both the $H2$ -Ne and $D2$ -Ne Van der Waals bimers, new infrared spectra have been obtained in the region of the $H2(orD2)$ monomer fundamental band region. We have used these new data in our least-squares fitting procedure to determine an improved potential energy surface for $H2-Ne$, which is based on the Exchange-Coulomb (XC) model of Meath and coworkers. In this paper, we will present the results of our analysis and compare the predictions of the XC potential with those obtained using a number of existing potentials.
