Nonmesomorphic Solute-Mesomorphic Solvent Interactions Studies .3. A Unified Approach to Probe Liquid-Crystalline Order by Electron-Spin-Resonance Spectroscopy
This paper reports values for the A and g magnetic tensor components for PD-Tempone in the rigid limit of the n-pentyl (5CB), n-hexyl (6CB), n-heptyl (7CB), and n-octyl (8CB) cyanobiphenyl liquid crystals and for Tempo-Palmitate in the rigid limit of 5CB and 6CB. A unified approach based on introducing a factor into the "distortion theory" expression for obtaining probe order parameters S-ii is successfully tested. The sign and value of this factor give the probability of alignment of the ith axis of the probe along the applied magnetic field.
