Can global target analysis of the splitting and spin relaxation from a ring-deuterated mesogen produce dynamical information?

We report on the measurements of quadrupolar splitting and spectral densiti es of motion for the phenylthio ring deuterons as a function of temperature in 4-pentylphenylthio-4'-octyloxy- benzoate ((8) over bar S5 - d(4)). A gl obal analysis of all these observables at 9 different temperatures in the n ematic and smectic A phases is shown to give useful information on the core dynamics of (8) over bar S5. Inclusion of the smectic C phase in the globa l analysis is possible; but gives a poorer overall fitting quality factor.
