Available in PDF, EPUB and Kindle. Book excerpt: This book presents a range of fundamentally new approaches to solving problems involving traditional molecular models. Fundamental molecular symmetry is shown to open new avenues for describing molecular dynamics beyond standard perturbation techniques. Traditional concepts used to describe molecular dynamics are based on a few fundamental assumptions, the ball-and-stick picture of molecular structure and the respective perturbative treatment of different kinds of couplings between otherwise separate motions. The book points out the conceptual limits of these models and, by focusing on the most essential idea of theoretical physics, namely symmetry, shows how to overcome those limits by introducing fundamentally new concepts. The book begins with an introduction to molecular symmetry in general, followed by a discussion of nuclear spin symmetry. Here, a new correlation between identical particle exchange and spin angular momentum symmetry of nuclei is exhibited. The central part of the book is the discussion of extremely floppy molecules, which are not describable in the framework of traditional theories. The book introduces a fundamentally new approach to describing the molecular dynamics of these molecules - the super-rotor model, which is based on a five-dimensional symmetry that has never been observed in molecules before. By applying the super-rotor theory to the prototype of floppy molecules, protonated methane, this model can consistently predict the symmetry and energy of low-energy states, which were characterized experimentally only a few years ago. The theoretical predictions agree with the experimental results, which makes the prospect of further developing the super-rotor theory and applying it to other molecules a promising one. In the final section, the book also covers the topic of ultrafast rotations, where usual quantum calculations reach their natural limits. A semi-classical method for determining rotational energies, developed in the early 1990s, is shown to be attachable to quantum calculations of the vibrational states. This new combined method is suitable for efficiently calculating ro-vibrational energies, even for molecular states with large angular momentum.

Download or read book Rotational Structure in Molecular Infrared Spectra written by Carlo di Lauro and published by Elsevier. This book was released on 2013-05-13 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in infrared molecular spectroscopy have resulted in sophisticated theoretical and laboratory methods that are difficult to grasp without a solid understanding of the basic principles and underlying theory of vibration-rotation absorption spectroscopy. Rotational Structure in Molecular Infrared Spectra fills the gap between these recent, complex topics and the most elementary methods in the field of rotational structure in the infrared spectra of gaseous molecules. There is an increasing need for people with the skills and knowledge to interpret vibration-rotation spectra in many scientific disciplines, including applications in atmospheric and planetary research. Consequently, the basic principles of vibration-rotation absorption spectroscopy are addressed for contemporary applications. In addition to covering operational quantum mechanical methods, spherical tensor algebra, and group theoretical methods applied to molecular symmetry, attention is also given to phase conventions and their effects on the values of matrix elements. Designed for researchers and PhD students involved in the interpretation of vibration-rotation spectra, the book intentionally separates basic theoretical arguments (in the appendices), allowing readers who are mainly concerned with applications to skip the principles while at the same time providing a sound theoretical basis for readers who are looking for more foundational information.

Download or read book Photofunctionalization of Molecular Switch Based on Pyrimidine Ring Rotation in Copper Complexes written by Michihiro Nishikawa and published by Springer Science & Business Media. This book was released on 2013-12-16 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a detailed description of photofunctionalization of molecular switch based on pyrimidine ring rotational isomerization in copper complexes bearing two bidentate ligands. The most important features of this work focus on the properties associated with the rotational isomerization based on the two possible coordination geometries at the copper center derived from two nitrogen atoms on the unsymmetrically substituted pyrimidine ring. The functions of systems such as dual emission and redox potential switching based on photo-driven rotation will be of particular interest to readers. Both the functions and the procedures for proving these phenomena are beneficial for the development of more functionalized systems based on material science, molecular science, nanoscience, nanotechnology, electrochemistry, photochemistry, coordination chemistry, physical chemistry, and related disciplines. The finding elucidated here holds promise for handling the photoprocesses of metal complexes, valid for both applications and novel properties. This system is expected make it possible to extract an electrochemical potential response from molecular switches, aiming to simulate the five senses of human beings at a single molecular level.
