Summary: High‐resolution FT‐IR spectroscopy has been used for the first time to characterize the variation of the unit cell dimensions of high‐density polyethylene (HDPE). In combination with the unit cell parameters of HDPE measured at different temperatures by Swan using wide‐angle X‐ray diffraction, the relationship between the rocking band shift (730 cm −1 ) and the change of the unit cell volume of HDPE has been established.High‐resolution variable‐temperature FT‐IR spectra of HDPE rocking bands with decreasing temperature.
