The far infra-red absorption spectrum of the compressed gas ethylene has been measured in the region 10–200 cm−1 at pressures from 14.7 to 55.7 bar at 296 K. The origin of the broad bands observed is a bimolecular collision induced absorption as indicated by the dependence of the total integrated intensity on the square of the molecular number density. The quantum theory [6] of resonant, multipole induction, giving rise to sets of rotational transitions is an inadequate description of the observed broad continua, the peaks of which shift from 125 cm−1 to 150 cm−1 over the pressure range investigated. However, they are matched satisfactorily by a spectral function c(ω), generated from an approximation to its related classical autocorrelation function c(t), containing two equilibrium averages Ko(o) and Kl(l) (which are related to the coefficients in the Maclaurin expansion of c(t)); and a width parameter γ. All three phenomenological parameters vary with pressure, contrary to the quantum prediction of their constancy, and go through a smooth minimum at . 30 bar, where the correlation time τ is longest.
