摘要: Proton spin–lattice relaxation rates 1/T1 are observed for the nematic liquid crystal PAA and its selectively deuterated species PAA‐d6 PAA‐d8 in isotropic states at frequencies of 15 55 MHz. The main process ring protons is thermal fluctuation order director, translational diffusion molecules also contributes to rate these protons. On other hand, methyl relax predominantly through phases. director makes a small contribution spin state near transition point.
