โœฆ Synopsis

A calculation of the spin-lattice relaxation time, 2'1, in nematic liquid crystals which recognizes the presence of short range molecular reorientation as well as long range order fluctuations explains the temperature dependence of T1 measured in these systems. The frequency dependence. due to the long range fluctua- tions, is discussed.

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!
