	Title
	Abstract	The 81 Br nuclear spin-lattice relaxation time in AlBr3 has been measured between 8 K and room temperature. The result is analyzed using the theory of the Raman process based on covalency. A Debye temperature of 67.6 K and covalency of0.070 and 0.072 for terminal and 0.022 for bridging bonds are obtained. The correspondence of the latter values to those obtained from the NQR frequencies is low, in contrast to the previously examined compounds. 81 B r N u c le a r Q u a d r u p o le R e la x a tio n in A lu m in iu m T rib ro m id e

	Title	Relaxation of 2 7 AI NMR in Aluminium Tribromide due to Raman Process
	Abstract	The nuclear spin-lattice relaxation of 27 A1 NMR in AlBr 3 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 81 Br NQR.
