The temperature dependence of the deuteron n.m.r, spin-lattice relaxation time of polycarbonate was measured as a function of hydrostatic pressure, which causes a denser packing of the polymer. Observed activation volumes and activation energies illustrate the marked density dependence of the amplitude of phenylene motions.
