Waltz and CSD ChemViz (short for chemistry visualization) is a set of web-based applications created by NCSA designed to catalyze a better understanding of chemical processes through visualization. Two tools are currently supported Waltz, which generates images and animations of desired molecules and ions and CSD, which presents a 3D model of complex organic compounds. http //chemviz.ncsa. uiuc.edu/...

Chemistry is by nature an abstract subject. First, it relies on a symbolic language based on chemical formulas and equations. Second, it is based on the behavior of atoms and molecules—particles far too small to see. By presenting chemistry visually, the authors help you to "see" the chemistry you need to learn and increase your success in the course.

Molecular orbitals were one of the first molecular features that could be visualized with simple graphical hardware. The reason for this early representation is found in the complex theory of quantum chemistry. Basically, a structure is more attractive and easier to understand when orbitals are displayed, rather than numerical orbital coefficients. The molecular orbitals, calculated by semi-empirical or ab initio quantum mechanical methods, are represented by isosurfaces, corresponding to the electron density surfeces Figure 2-125a). 

The visualization of volumetric properties is more important in other scientific disciplines (e.g., computer tomography in medicine, or convection streams in geology). However, there are also some applications in chemistry (Figure 2-125d), among which only the distribution of water density in molecular dynamics simulations will be mentioned here. Computer visualization of this property is usually realized with two or three dimensional textures [203]. 

The JME Editor is a Java program which allows one to draw, edit, and display molecules and reactions directly within a web page and may also be used as an application in a stand-alone mode. The editor was originally developed for use in an in-house web-based chemoinformatics system but because of many requests it was released to the public. The JME currently is probably the most popular molecule entry system written in Java. Internet sites that use the JME applet include several structure databases, property prediction services, various chemoinformatics tools (such as for generation of 3D structures or molecular orbital visualization), and interactive sites focused on chemistry education [209]. 

Organic chemistry is a very visual science and computer modeling is making it even more so... 

Carotenoids absorb visible light (Section 13 21) and dissipate its energy as heat thereby protecting the organism from any potentially harmful effects associated with sunlight induced photochemistry They are also indirectly involved m the chemistry of vision owing to the fact that p carotene is the biosynthetic precursor of vitamin A also known as retinol a key substance m the visual process...

The use of graphic displays as an essential element of computer-based instmctional systems has been exploited in a number of ways. Molecular modeling and visualization techniques have supplemented the traditional set of stick models in courses on organic and inorganic chemistry, and animation of molecular motion and of the progress or mechanism of chemical reactions has been a useful classroom tool. 

Two successful and widespread appHcations of visualization techniques in the field of chemistry are the visualization of molecular orbitals and the visualization of molecules in molecular mechanics studies. 

Oxygen corrosion involves many accelerating factors such as the concentration of aggressive anions beneath deposits, intermittent operation, and variable water chemistry. How each factor contributes to attack is often difficult to assess by visual inspection alone. Chemical analysis of corrosion products and deposits is often beneficial, as is more detailed microscopic examination of corrosion products and wasted regions. 

One should not be perturbed by different experts preferences for different kinds of polyhedra after all, these are no more than a visual aid to understanding. The key thing is that different aspects are intimately related... in these figures, every point is linked to every other point. Each of these aspects, whether they be divided into four or six categories, needs a familiarity with. some of the classical disciplines such as physics, chemistry, physical chemistry, and with subsidiary not-quite-independent sciences such as rheology and colloid science.
