Determination of molecular orientation distribution
of a stable paramagnetic probe in oriented 4-cyano-4´-n-pentylbiphenyl
A. Kh. Vorob´ev* and N. A. Chumakova
The molecular orientation distribution function of a stable radical 4-hydroxy-2,2,6,6-
tetramethylpiperidine-1-oxyl in magnetic-field oriented 4-cyano-4´-n-pentylbiphenyl was determined from the angular dependence of the ESR spectra. The preferred molecular orientation of radical species in the liquid-crystal matrix was determined. The temperature evolution
of the orientation distribution function was studied.
