Popis:	Proton spin–lattice relaxation has been studied in the nematic phase of MBBA and MBBA-d8 samples. The proton T1 temperature dependence appears to come from the motions of side chains as in p-azoxyanisole. Order of magnitude calculations of T1 based on order fluctuations agree with the ring proton T1. The proton T1 frequency dispersion of MBBA at 18 °C can be explained by order fluctuations plus a frequency dependent B term without any cutoff in the hydrodynamic modes.
