Abstract
The infrared spectrum of the acetylene-nitrous oxide van der Waals complex has been observed in the three micron wavelength region, corresponding to excitation of the asymmetric hydrogen stretching vibration of the acetylene monomer. Preliminary analysis of this spectrum gives $A^{-}=9385, B^{-}=2834, C_{2}=2170, A_{2}=9390. B_{2} =2830$, and $C=2167 MHz$. The vibrational origin for the transition is $3281.544 cm^{-1}$. The rotational constants are consistent with a geometry having the axes of the two monomers parallel to one another and the centers of mass of each monomer directly opposite each other. This geometry is almost indistinguishable from that of the acetylene-carbon dioxide complex.
