Abstract
The structure of carbon dioxide-acetylene, discussed in the previous paper, was that predicted by the quadrupole-quadrupole interaction. Identical considerations apply to acetylene-nitrogen, and the symmetric parallel geometry was anticipated. However, the observed infrared spectrum is that of a linear molecule. Two hot bands are observed, along with the fundamental transition. Numerous perturbations are also present. The vibrational origin of the fundamental occurs at $3283.093 cm^{-1}$ with $B^{\prime \prime}=1502$ MHz and $B^{\prime} =1507 MHz$. These rotational constants give a centers of mass separation for the monomers of 4.822 {\AA} and 4.815 {\AA}, respectively. Low frequency bending vibrations will be discussed in terms of a distributed multipole potential function.
