We present a quantitative analysis of the spectral density data from the core and chain deuterons in the liquid crystal p-hexyloxybenzylidene-pX-fluoroaniline. The unusually small J1Žv.rJ2Ž2v. ratio for the methylene deuterons near the core in the highly ordered smectic B phase is reproduced using a decoupled model for correlated internal bond rotations in the chain.

Abstract
We present a quantitative analysis of the spectral density data from the core and chain deuterons in the liquid crystal p-hexyloxybenzylidene-pX-fluoroaniline. The unusually small J1Žv.rJ2Ž2v. ratio for the methylene deuterons near the core in the highly ordered smectic B phase is reproduced using a decoupled model for correlated internal bond rotations in the chain.File in questo prodotto:
