This book, devoted exclusively to symmetry in chemistry and developed in an essentially nonmathematical way, is a must for students and researchers. Topics include symmetry elements and operations, multiple symmetry operations, multiplication tables and point groups, group theory applications, and crystal...
Symmetry is all around us. Our eyes and minds are drawn to symmetrical objects, from the pyramid to the pentagon. Of fundamental significance to the way we interpret the world, this unique, pervasive phenomenon indicates a dynamic relationship between objects. In chemistry and physics, the concept...

Examples are present in tetrahedral silicon tetrafluoride, with three S4 axes, and the staggered conformation of ethane with one S6 axis. Identity, abbreviated to E, from the German 'Einheit' meaning Unity. This symmetry element simply consists of no change: every molecule has this element. ...

4 Symmetry and crystal field theoryThe EPR spectra of solid metal compounds are greatly influenced by the coordina-tion environment of the paramagnetic ion which causes shifts in the energy statesof the ion. The“ligands”that make up the coordination environment of transitionmetal and rare earth ...
Symmetry in Science 2024 pdf epub mobi 电子书 图书描述 Symmetry plays an essential role in science - not only in crystallography and quantum theory, where its role has long been explicitly recognized, but also in condensed-matter physics, thermodynamics, chemistry, biology, and others. This text...
The family constitutes a new class of asymmetric kernels, and it consists of a specific functional form and a set of common conditions, as in Definition 1 below. The name “GG kernels” comes from the fact that the pdf of a GG distribution by Stacy [36] is chosen as the functional ...
