Lattice Dynamics of Molecular Crystals and Weak Chemical Interactions

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 weak chemical interactions in molecular crystals, presenting the concept of weak chemical interactions based on experimental study of a wide class of molecular crystals. Primarily written for physical and organic chemists, scientists, and engineers involved in crystal engineering and the synthesis and design of molecular crystals and crystalline structures containing weak chemical interactions, this book is also ideal for anyone investigating lattice dynamics probed by Raman spectroscopy, including a diverse range of chemists and physicists.Provided 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 behavior of a proton on a hydrogen bond.Covers in-depth intermolecular chemical interactions, weak and strong hydrogen bonds, van der Waals interactions, and halogen bondsProvides a detailed study of bonding in different types of compounds and crystalsUses temperatures in the range of 5 K-300 K as a soft influence on the lattice parameters of the crystalOutlines the recording of polarized and unpolarized Raman spectra of crystals in a wide temperature rangeDemonstrates careful processing of the spectra to obtain the temperature dependence of all parameters of the vibrational mode (frequency, half-width, and intensity)
