Elsevier Lattice Dynamics of Molecular Crystals and Weak Chemical Interactions: Investigation using Raman Spectroscopy Methods

Weak chemical interactions (van der Vaals, halogen and hydrogen bonding) establish the structure of molecular crystals. Even if the nature of van der Vaals interaction is now well understood and described, then the essence of halogen and hydrogen bonds is still debated. Understanding their nature is crucial for the design and synthesis of organic, pharmaceutical and biological systems, as well as for predicting the main physicochemical properties of synthesized objects. Lattice Dynamics of Molecular Crystals and Weak Chemical Interactions: Investigation using Raman Spectroscopy Methods shows how to fully exploit the capabilities of Raman spectroscopy in the study of weak chemical interactions in molecular crystals. It presents the concept of weak chemical interactions based on experimental study of a wide class of molecular crystals. Information on the temperature dependence of the parameters of vibrational modes makes it possible to obtain information on the potential of intermolecular interaction, the degree of its anharmonicity, the orientational mobility of molecules in a crystal, structural phase transitions, and the behaviour of a proton on a hydrogen bond. Lattice Dynamics of Molecular Crystals and Weak Chemical Interactions: Investigation using Raman Spectroscopy Methods is written primarily for physical and organic chemists as well scientists and engineers involved in crystal engineering and the synthesis and design of any molecular crystals and crystalline structures containing weak chemical interactions. It will also be of use to anyone investigating lattice dynamics probed by Raman spectroscopy, including a diverse range of chemists and physicists or those whose interests lie in the fields of biological or pharmaceutic systems. Covers in-depth intermolecular chemical interactions, weak and strong hydrogen bonds, van der Waals interactions, and halogen bonds Provides a detailed study of bonding in different types of compounds and crystals Uses temperatures in the range of 5 K–300 K as a soft influence on the lattice parameters of the crystal Outlines the recording of polarized and unpolarised Raman spectra of crystals in a wide temperature range Demonstrates careful processing of the spectra to obtain the temperature dependence of all parameters of the vibrational mode (frequency, half-width and intensity)
