dc.description.abstractThe collision-induced first overtone band of $H_{2}-Ar$ gas mixtures was observed at 160 K and pressures up to 1700 atm. Previous studies at low densities showed the enhancement by argon of the three single $H_{2}$ overtone transitions $Q_{2}(1)$, $S_{2}(0)$ and $S_{2}(1)$. The present work shows that with a constant $H_{2}$ density and increasing argon densities the double $H_{2}$-transitions $Q_{1} (1,0) + Q_{1}(1)$ and $Q_{1}(1,0)+S_{1} (1)$ begin to appear at argon densities of $\sim $400 amagat. The results have two interesting features: (1) the intensities of the double $H_{2}$ transitions increase more rapidly with Ar density than the single $H_{2}$ transitions, (2) the half-widths of the double transitions are $ \sim 25 \%$ less than the half-widths of the single $H_{2}$ transitions. The implication of these results for the molecular dynamics of high density studies will be discussed.en_US
