Calculations of intramolecular and intermolecular interactions, giving the contributions to the nuclear magnetic resonance second moment for poly(p-phenylene sulfide) (PPS), have been carried out. Second-moment values of the PPS rigid lattice before and after heat treatment have been measured. Good agreement between theoretical and experimental data has been obtained. The parameters of the unit cell for the PPS 'asymmetric model' have been determined.
