Abstract

Abstract The nuclear spin-lattice relaxation of 27Al NMR in AlBr3 has been examined from 25 to 320 K. The result is analyzed using a theory of the Raman process based on covalency. A Debye temper-ature of 118 K is obtained together with a covalency larger than that obtained from the relaxation in the 81Br NQR.
