The aim of this book is to provide an introduction to all those who wish to use the complementary spectroscopic techniques of optical activity (circular dichroism, CD) and optical anisotropy (linear dichroism, LD) for the study of the structure of molecules and interactions between molecules in solution. The emphasis of the book is on what the techniques are and how to use them for both low and high molecular weight molecules. It is intended to be an easy guide to what a prospective user of CD needs to know and explains how LD is not merely an exotic technique only to be practised by experienced spectroscopists, but may be routinely and usefully employed as an aid to molecular structure determination.Circular Dichroism and Linear Dichroism is the first book that is an easy, directly applicable manual to the use and interpretation of both CD and LD. It will be of use to both novices and experienced researchers in the field.
