Abstract

A general procedure for simulating EPR spectra of partially oriented paramagnetic centers is presented. The procedure is applied to the systems of [Ni(maleonitriledithiolato)₂]^- in oriented nematic N-(4′-methoxybenzylidene)4-n-butylaniline liquid crystal and to consolidated clays. The Ni(mnt)₂^- case is unusual in that the long, in-plane molecular axis tends to align with the liquid crystal, while for the clay, no g-tensor axis is colinear with the axis of orientation. With the present development, the degree of orientation in a wide range of partially ordered systems can now be quantitatively analyzed.
