The sensitivity of the solid-state deuterium NMR line shape to the motion of the C-D bond is exploited to investigate the state of phenanthrene-d10 in zeolites with various counterions. NMR line-shape analysis and measurement of the relaxation time of the Zeeman order (T1) support the existence of two independent spin reservoirs. Spectral line shapes are decomposed into contributions from each spin reservoir to determine equilibrium constants for ion-phenanthrene association as a function of temperature. ΔH for this process decreases with increasing cation radius.
