Structure of Free Polyatomic Molecules


Book Description

This volume Structure of Free Polyatomic Molecules Basic Data contains frequently used data from the corresponding larger Landolt-Börnstein handbooks in a low price book for the individual scientists working in the laboratory. Directories link to the more complete volumes in the library. The book contains important information about a large number of semiconductors.




Structure Data of Free Polyatomic Molecules


Book Description

This handbook presents structural data on free polyatomic molecules. Since the structure of molecules defines the chemical, physical and biological properties of matter, this information is crucial for understanding, explaining and predicting chemical reactions and biochemical processes, developing new drugs and materials as well as studying interstellar media. Covering the structural data published between 2009 and 2017, this book supplements the previous Landolt–Börnstein volumes “Structure Data of Free Polyatomic Molecules” (eds. K. Kuchitsu, N. Vogt, M. Tanimoto), which included data from the literature published up to 2008. It systematizes and describes peculiarities of molecular structures for about 1000 compounds studied mainly by gas-phase electron diffraction and rotational spectroscopy. All structures are given in three-dimensional representations.




Equilibrium Structure of Free Molecules


Book Description

The properties of chemical, pharmaceutical, and biological compounds depend mainly on their molecular structure, whose determination is of fundamental interest. This book examines and systematizes more than three hundred striking structural determinations of free molecules. Featuring high-quality structural data and presenting modern techniques of their determinations by quantum chemistry, high-resolution spectroscopy and electron diffraction, the book is an indispensable resource for graduate students and professional scientists specializing in structural chemistry and other related fields.




Structure Data of Free Polyatomic Molecules


Book Description

Since the publication of Volumes II/7 in 1976 and its supplements II/15 in 1987 and II/21 in 1992, the information on the structure of free molecules in the ground state and in excited electronic states has increased considerably. Therefore this volume II/23 contains data from 148 inorganic and 498 organic polyatomic free molecules (including free radicals and molecular ions) published between 1990 and 1993 inclusively and a small number of structures published 1994. All experimental methods for the determination of structural data of free molecules have been considered, all data obtained by these methods have been critically evaluated and compiled. The structural data for more than 3400 polyatomic free molecules can be completely surveyed and easily retrieved by means of this volume.




Accurate Structure Determination of Free Molecules


Book Description

This book presents a detailed look at experimental and computational techniques for accurate structure determination of free molecules. The most fundamental property of a molecule is its structure – it is a prerequisite for determining and understanding most other important properties of molecules. The determination of accurate structures is hampered by a myriad of factors, subjecting the collected data to non-negligible systematic errors. This book explains the origin of these errors and how to mitigate and even avoid them altogether. It features a detailed comparison of the different experimental and computation methods, explaining their interplay and the advantages of their combined use. Armed with this information, the reader will be able to choose the appropriate methods to determine – to a great degree of accuracy – the relevant molecular structure.

Polyatomic Molecules


Book Description

Polyatomic Molecules: Results of Ab Initio Calculations describes the symmetry of polyatomic molecules in ground states. This book contains 12 chapters that also cover the excited and ionized states of these molecules. The opening chapter describes the nature of the various ab initio computational methods. The subsequent four chapters deal with the three-atom systems, differing with respect to the number of hydrogen atoms in the molecules. These chapters also discuss the reaction surfaces of these systems. These topics are followed by discussions on the molecules whose ground states belong to relatively high, little or no symmetry groups. The concluding chapters explore the inorganic and relatively large organic molecules. These chapters also examine the ab initio calculations of molecular compounds and complexes, as well as hydrogen bonding and ion hydration. This text will be of great value to organic and inorganic chemists and physicists.
