Abstract: Studies in the past on the infrared absorption of the fundamental bands of symmetric diatomic molecules induced by collisions in binary mixtures with polar gas molecules have been very meagre. We now report the results of a study on the induced infrared absorption of the fundamental band of deuterium in $D_{2}-CO$ mixtures. The band was studied at room temperature at a path length of 105.2 cm at various pressures of the mixtures up to 110 atmospheres for several base pressures of deuterium. Integrated absorption coefficients were measured and the binary and ternary absorption coefficients were derived. The values of the binary and ternary coefficients are as follows: $\alpha_{1b}=(2.61 \pm 0.01)\times 10^{-2} cm^{-2} Amagat^{-2};\alpha_{2b}=(3.9 \pm 0.1)\times 10^{-6} cm^{-2} Amagat^{-3}.$ The experimental enhancement absorption profiles of the band in $D_{2}-CO$ mixtures were discussed and compared with those obtained in $D_{2}-N_{2}$ mixtures where the perturbing molecule $N_{2}$ is iso-electronic with CO.
