Dynamics of n-hexane inside silicalite, as studied by (super 2)H NMR:

Perdeuterated n-hexane, adsorbed in silicalite, is found to exhibit a 2H NMR spectrum that represents a superposition of three Pake-powder patterns. Interpretation of the separate line shapes contributing to the total (super 2)H NMR spectrum of the adsorbed alkane and the temperature dependence of the spin-lattice relaxation time T1 is made in terms of different mobilities, exhibited by different CD(sub n) groups of the adsorbed alkane.
