Resumen:
The NMR spin-lattice proton relaxation dispersion T1( nL) of the liquid crystal propylcyanophenylcyclohexaneis studied over several decades of Larmor frequencies and at different temperatures in thenematic mesophase. The results show that the order fluctuation of the local nematic director contribution toT1( nL) undergoes a transition between two power regimes: from T1( nL)} nL1/2 to n a;1/3) on going fromlow to high Larmor frequencies.
