V. Rizi et Sk. Ghosh, ON THE DYNAMIC CRITICAL-BEHAVIOR ABOVE THE NEMATIC-ISOTROPIC TRANSITION IN 8CB, Nuovo cimento della Societa italiana di fisica. D, Condensed matter,atomic, molecular and chemical physics, biophysics, 15(4), 1993, pp. 661-668
We report here a study on the dynamic critical behaviour (DCB) at the
nematic-isotropic (NI) transition in 8CB using the frequency and tempe
rature dependences of proton spin-lattice relaxation rates. Both these
dependences and the DCB are very similar in all the members of the cy
anobiphenyl series measured so far. The DCB is also similar to that ob
served in MBBA although the frequency dependence of the total relaxati
on rates is slightly different.
