The effect of intermolecular interactions on the skeltal vibration frequencies of the isotactic polypropylene crystal active in the IR spectrum is theoretically estimated. A simplified model of the molecule is employed. The Kitaigorodskii potential function is used for the intermolecular atom—atom interactions. The results are given in the form of a frequency table.
