Abstract
QENS data for the <(7)over bar S5> liquid crystal (both hydrogenous an d chain-deuterated samples) have been analysed from a probabilistic (B ayesian) point of view. When a physical model cannot be proposed for a given reorienting system, it is appropriate to use probability theory to assess how many quasi-elastic components there is most evidence fo r in the data. A ''component'' can be thought of both as a single Lore ntzian or as a more complex, non-lorentzian lineshape.
