NMR Spectra in Liquid Crystals the Partially Averaged Spin Hamiltonian,by the anisotropic molecular tumbling. Moreover, since the degree of the averaging processes depends on the orientational distribution, the equilibrium values of magnetic interactions, measurable from splittings and line positions in the NMR spectra, are functions of the orientational order.

Determination of Biaxial Structures in Lyotropic Materials by Deuterium NMR,ravel. This range is . where D is the diffusion constant and τ the length of the free induction decay. Normally in liquid crystals D ~ 10. cm./sec and τ ~ 10. sec in which case R ~ 1000 ?. This number may be smaller or larger by roughly an order of magnitude depending upon the system.
