✦ Synopsis

The proton spin-lattice relaxation time has been measured in the solid, nematic and isotropic phases of EBBA [N-~~thoxybenzylidene)9_butylanilinel. TWO IIIinima Were found in the te.nperature dependence of T, in the solid phase. In !he nematic and isotropic phase, the relaxation mechanism can be c!wracterized by activation energies of 5.9 kul/mole and 8.8 k&/mole, respectively.
