摘要：

We present a quantitative analysis of the spectral density data from the core and chain deuterons in the liquid crystal p-hexyloxybenzylidene-p'-fluoroaniline. The unusually small J(1)(omega )/J(2)(2 omega) 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.
