dc.description.abstractThe collision-induced fundamental infrared absorption band of hydrogen in $H_{2}-He$ and $H_{2}-Ne$ mixtures at $77^{\circ} K$, $195^{\circ} K$, $273^{\circ} K$ and $298^{\circ} K$ has been studied for gas densities up to 530 amagat for several base densities of hydrogen. In each of these mixtures the enhancement absorption profiles show, in addition to the usual splitting of the Q branch into the main $Q_{P}$ and $Q_{R}$ components, a splitting of the S(1) line into $S_{P}$(1) and $S_{R}$(1) components at all the experimental temperatures, and a secondary splitting of the main $Q_{P}$ component into the $Q_{P}$(3) and $Q_{R}$(3) components at $273^{\circ} K$ and $298^{\circ} K$. The profiles of $H_{2}-He$ at $77^{\circ} K$ also show a splitting of the S(0) line into $S_{P}$(0) and $S_{R}$(0). Integrated absorption coefficients were measured and binary and ternary absorption coefficients were derived. Van Kranendonk’s theory of the `exp-4^{\prime} model for the induced dipole moment was applied to the experimental binary absorption coefficients. The overlap parts of these coefficients were obtained from the experimental values by subtracting the quadrupolar parts, calculated from the known molecular parameters. The overlap parameters $\lambda$ and $\rho$, giving respectively the magnitude and range of the overlap moment, were then determined for each of the mixtures by obtaining the best fit of the calculated overlap part of the binary absorption coefficient as a function of temperature to the experimental values of the overlap parts. The values of $\lambda$ and $\rho$ are as follows: “figure”en_US
