Abstract Eigenvectors of vibrating polyethylene chains with (200) and (110) folds have been calculated by solving the phonon-scattering problem exactly with the method of Green's function. The results are applied to analyze the resonance modes of the (200) fold (ggtgg: 1353, 1356, 1374 cm−1) and the (110) fold (approximately g′g′ggtg: 820, 1288, 1342, 1348, 1372, 1374 cm−1) in terms of the characteristic vibrations of smaller subunits of the (200) fold (gg, gtg) and the (110) fold (g′g′ggtg, g′g′gg, gtg) which can be identified spectroscopcally.
