摘要：
27Al NQR responses have been obtained from the three different forms of crystalline Al2SiO5, andalusite, kyanite, and sillimanite, by a very sensitive Robinson-type continuous wave NQR spectrometer at 77 K or at room temperature. From the NQR responses the values of Qcc and of η were determined for all the aluminum coordinations in the powdered samples. The values are compared with those obtained by nuclear magnetic resonance studies of single crystals. © 1991.
