Partial orientation of cytochrome c in a lyotropic liquid crystal: Residual H-H dipolar coupling
Article Abstract:
It is shown that dissolving a paramagnetic protein in lyotropic liquid crystal solvent results in measurable splittings of several hyperfine-shifted proton lines, without excessive broadening. These splittings are due to residual dipolar coupling of neighboring geminal protons and are interpreted in terms of an orientation tensor, whose magnitude corresponds to about 1 percent orientation.

Domain growth scaling at the isotropic-to-cholesteric liquid crystal transition
Article Abstract:
The phase-ordering kinetics for the growth of the ordered cholesteric liquid crystalline phase from the disordered isotropic melt is investigated at isothermal conditions after a temperature quench. The short-term nucleus growth process is found to be dependent on the sample confinement with increasing growth exponents as the cell gap in increased.

Transverse nuclear spin relaxation due to director fluctuations in liquid crystals - a slow-motional theory
Article Abstract:
The transverse nuclear spin relaxation measurements that use the Carr-Purcell-Meiboom-Gill sequence can provide detailed information on the dynamics of director fluctuations in liquid crystals. A general analysis of the transverse magnetization decay in different kinds of experiments is presented.
