Abstract

The longitudinal proton spin relaxation time T1 was measured over a broad range of Larmor frequencies w in the nematic and isotropic phases of the liquid crystal Hexyloxyazoxybenzene, deuterated on the benzene rings (60AB-D8). All the measurements were made on a Fast Field-Cycling Spectrometer [1]. Our analysis also takes into account T1 data from the literature [2].
