A study of cyclohexane, piperidine and morpholine with X-ray diffraction and molecular simulations

In this work, the EDXD/molecular dynamics approach to the study of molecular liquids, is applied to cyclohexane and two substituted analogues, piperidine and morpholine. The Structure Functions and Radial Distribution Functions obtained from EDXD (Energy Dispersive X-ray Diffraction) scattered intensity data are interpreted with the same theoretical model recently used for unsaturated liquids. The agreement obtained is satisfactory, although a bit lower in this case. The models are then refined through least-squares fitting to experimental data. (c) 2007 Elsevier B.V. All rights reserved.
