This lists the character tables for the more common molecular point groups used in the study of molecular symmetry.These tables are based on the group-theoretical treatment of the symmetry operations present in common molecules, and are useful in molecular spectroscopy and quantum chemistry.
A unit tesseract has side length 1, and is typically taken as the basic unit for hypervolume in 4-dimensional space. The unit tesseract in a Cartesian coordinate system for 4-dimensional space has two opposite vertices at coordinates [0, 0, 0, 0] and [1, 1, 1, 1], and other vertices with coordinates at all possible combinations of 0 s and 1 s.
The diamond lattice can be viewed as a pair of intersecting face-centered cubic lattices, with each separated by 1 / 4 of the width of the unit cell in each dimension. Many compound semiconductors such as gallium arsenide , β- silicon carbide , and indium antimonide adopt the analogous zincblende structure , where each atom has nearest ...
A molecular model is a physical model of an atomistic system that represents molecules and their processes. They play an important role in understanding chemistry and generating and testing hypotheses.
Quantities, Units and Symbols in Physical Chemistry, also known as the Green Book, is a compilation of terms and symbols widely used in the field of physical chemistry. It also includes a table of physical constants , tables listing the properties of elementary particles , chemical elements , and nuclides , and information about conversion ...
One special case is the unit cube, so-named for measuring a single unit of length along each edge. It follows that each face is a unit square and that the entire figure has a volume of 1 cubic unit. [ 5 ] [ 6 ] Prince Rupert's cube , named after Prince Rupert of the Rhine , is the largest cube that can pass through a hole cut into the unit cube ...
Skeletal structural formula of Vitamin B 12.Many organic molecules are too complicated to be specified by a molecular formula.. The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are connected to one another.

A cubicle is also called a cubicle desk, office cubicle, cubicle workstation, or simply a cube. An office filled with cubicles is sometimes called a sea of cubicles, and additionally called pods (such as 4-pod or 8-pod of cubes) [6] or a cube farm. Although humorous, the phrase usually has negative connotations. [7]
