Abstract

D nmr lineshape information was obtained from the echo response following a pair of phase shifted pulses using a method first proposed by Clark. In this manner the D quadrupole coupling constant and asymmetry parameter for D₂O in p-dioxane•17D₂O were found to be 217 kHz and 0.10 at 63 K. The D nmr lineshape for ethylene oxide-d₄•7H₂O shows that at 17 K the guest molecules are held rigidly in their cages. At higher temperatures the doublet lineshape collapses to a broad structureless line characteristic of molecules for which the reorientational modes vary from cage to cage.
