The Skeletal Modes of Vibration of Long Chain Molecules

摘要

The method of Born, Karman and Blackman, designed for the determination of the normal modes of crystals, offers interesting possibilities in the case of certain polyatomic molecules possessing structural periodicity. The applicability of the method as a means of approximating the skeletal frequencies of the normal paraffin hydrocarbons is investigated. Although the calculations are not carried beyond the qualitative stage, they provide rather illuminating results.
