Abstract : The pressure-induced infrared absorption spectrum of gaseous methane was observed using a 10m cell and 4-10 atm. pressure in the region 200-550 cm. The intensity can be expressed according to the relation: A(nu) = gamma(nu)(d sq), where A(nu) is the absorbance at frequency nu, and d is the gas density. The spectrum is interpreted in terms of rotational transitions in a pair of CH4 molecules possessing a transient dipole moment induced by the octopole moment of the molecule. (Author)
