Abstract
Electron paramagnetic resonance measurements of the lag angle between the director and an external magnetic field for a nematic liquid crystal spinning about an axis oriented arbitrarily with respect to the field are reported. It is shown that the rotational frequency range in which the director distribution is essentially uniform increases rapidly as the rotation axis-applied field angle is reduced from 90°. The results indicate that magnetic torque measurements should be sufficient to determine both the rotational viscosity coefficient and the anisotropic part of the diamagnetic susceptibility.
