title: Collision-induced absorption at wavelengths near 5 microm by dense hydrogen gas.
abstract: Based on a recent ab initio interaction-induced dipole surface of collisionally interacting molecular hydrogen pairs H(2)-H(2), we compute the binary absorption coefficients at wavelengths near 5 microm at temperatures of 77.5 and 297 K for comparison with existing laboratory measurements. We observe satisfactory agreement of the measurements with our calculations, thereby concluding an earlier study [Gustafsson et al., J. Chem. Phys. 119, 12264 (2003)], which was based on an ab initio interaction-induced dipole surface that was inadequate for the 5 microm band.
