A method and apparatus for determining the effects of pressure and/or dissoved gas on the molecular dynamics in solids, such as glassy polymers, or gases sorbed by the solids, involves the use of nuclear magnetic resonance (NMR) spectroscopy wherein a pressure resistant sample cell is combined with an NMR probe which in turn is subjected to a magnetic field, a diffusion gas being injected into the sample cell under varying pressure with resultant NMR spectra being collected and correlated.
