VCD spectroscopy as a novel probe for chirality transfer in molecular interactions

Abstract

Most of the research in contemporary physical chemistry is devoted to the development of methods that extend our understanding, interpretation, and capacity to predict structural properties and dynamic behavior of molecules. The optical and magnetic spectroscopies, as well as diffraction techniques, are the principal methods for studying properties of molecules, biomolecules, and biopolymers of which the vast majority are chiral. On the other hand, information on molecular configuration can be obtained mainly from optical spectroscopies because other well-established spectroscopic techniques used for structural investigations, such as crystallographic, ESR, and NMR methods, do not allow for registration of signals from an individual conformer owing to intrinsic slow response to structural changes. This is the reason why the optical spectroscopy methods, based on natural chiroptical phenomena, have become so important and their renaissance in the last decade is noticed. Vibrational circular dichroism (VCD) spectroscopy is one such chiroptical technique that sheds new light on many important phenomena studied intensively. We provide an overview of recent theoretical predictions and innovative VCD observations of chirality transfer (called by other authors “induced chirality”) from a chiral molecule to an achiral one as a result of hydrogen bond interactions between them. In this tutorial review we search for answers as to whether we can obtain further information about intermolecular interactions using the VCD technique. In our opinion this technique has opened new horizons for both understanding and monitoring intermolecular interactions and it could be used as a relatively new and powerful physicochemical method.
