Abstract
Structural properties of the cholesteryl acetate have been investigated by Raman spectroscopy. In this work, we present Raman spectroscopy studies of the C=O stretching mode for this eater of cholesterol in the crystalline an d isotropic liquid phases. Our interpretation of the structural organizatio n is compared with some semi-empirical quantum calculations. A hypothesis i s suggested in order to explain the difference between our Raman spectrosco py investigations and the X-ray results. (C) 2000 Elsevier Science S.A. All rights reserved.
