We present a quantitative analysis of the spectral density data from t
he core and chain deuterons in the liquid crystal p-hexyloxybenzyliden
e-p'-fluoroaniline. The unusually small J(1)(omega )/J(2)(2 omega) rat
io for the methylene deuterons near the core in the highly ordered sme
ctic B phase is reproduced using a decoupled model for correlated inte
rnal bond rotations in the chain. (C) 1998 Elsevier Science B.V. All r
