Collision-induced infrared absorption spectra of the double vibrational transitions of $H2(v=1\leftarrow 0)+D2(v=1\leftarrow 0)$ have been investigated in their binary mixtures in the observed spectral region $5900-7100cm-1$. The spectra were recorded with a 2 m absorption cell for partial densities of $H2$ and $N2$ 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: $O1(J)$ of $H2+Q1(J)$ of $N2;Q1(J)$ of $H2+O1(J)$ of $H2;Q1(J)$ of $H2+Q1(J)$ of $N2;S1(J)$ of $H2+Q1(J)$ of $N2$. Analysis of the absorption profiles has been carried out. Similar experiments with binary mixtures of $D2+N2$ are also in Progress. The results of this work including the absorption coefficients, line-shape function, etc, will be presented.
