A hybrid hydrazine-nitroxide monoradical and the corresponding heterohydrazyl- nitroxide diradical were used as probes in 4-cyano-4- pentylbiphenyl liquid crystal. EPR data (hyperfine constants, rotational time, and anisotropy parameter values) are reported in the range of 25C-55C. It was shown by EPR spectrometry that the nitroxide moiety gives an anisotropic triplet line, while the hydrazyl moiety cannot be detected under these conditions. Taylor and Francis Group, LLC.
