Abstract
Collision-induced infrared absorption spectra of the double vibrational transitions of $H_{2} (v=1 \leftarrow 0) + D_{2}(v=1 \leftarrow 0)$ have been investigated in their binary mixtures in the observed spectral region $5900 -7100 cm^{-1}$. The spectra were recorded with a 2 m absorption cell for partial densities of $H_{2}$ and $N_{2}$ in the range 60 to 315 and 100 to 315 amagat. Respectively, at room temperature. The spectra are interpreted in terms of the following transitions: $O_{1}(J)$ of $H_{2} + Q_{1}(J)$ of $N_{2}; Q_{1}(J)$ of $H_{2} + O_{1}(J)$ of $H_{2}; Q_{1}(J)$ of $H_{2} + Q_{1}(J)$ of $N_{2}; S_{1}(J)$ of $H_{2} + Q_{1}(J)$ of $N_{2}$. Analysis of the absorption profiles has been carried out. Similar experiments with binary mixtures of $D_{2} + N_{2}$ are also in Progress. The results of this work including the absorption coefficients, line-shape function, etc, will be presented.
