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 l
## Abstract The proton NMR spectrum of azulene has been investigated in the nematic phase of a liquid crystal. Spectral analysis provided the direct dipole‐dipole coupling constants which were used to derive the structural information. It was found that the relative proton‐proton distances in the 7
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!
## Abstract Proton NMR spectra of dibenzofuran and dibenzothiophene were investigated in the nematic phase of liquid crystals. Dipolar couplings obtained from the spectral analysis were used to derive the inter‐proton distance ratios. Deviations from planarity were observed in both molecules, and a
