Prettl, Wilhelm and Frank, W. F. X. (1979) Interference distortion of the 73 cm−1 absorption line in polyethylene. Infrared Physics 19 (3-4), pp. 491-495.
The decrease of the absorption strength of the 73 cm−1 line in polyethylene and the strong antiresonance occuring above 310K at the high frequency side of the line are explained by assuming a Fano type coupling between the 73 cm−1 phonon and a continuum of infrared active vibrational modes. The parameters determining the line shape are deduced from experimental absorption curves and conceivable coupling mechanisms are discussed.
