The infrared absorption spectrum of the carbon dioxide--acetylene van der Waals complex has been observed in a pulsed molecular beam. A color center laser was used to excite the vibration associated with the antisymmetric hydrogen stretching mode of the acetylene monomer. The vibrational origin is 3281.740 cm/sup -1/ and the rotational constants are A'' = 8876, B'' = 2859, C'' = 2155, A' = 8864, B' = 2855, and C' = 2154 MHz. The axes of the two monomer are parallel to one another and the complex has C/sub 2//sub v/ symmetry. The separation of the monomer units is 3.285 A. The angular part of the intermolecular potential function is discussed in terms of electrostatic interactions between distributed multipole moments.
