Crystallographic information provides the fundamental basis for understanding the properties and behavior of materials. This data, such as chemical composition, unit cell dimensions, space group, and atomic positions, derives from the primary literature--that is, from published experimental measurement or theoretical calculation. Although the…

A Web site is described that facilitates use of the free computational chemistry software: General Atomic and Molecular Electronic Structure System (GAMESS). Its goal is to provide an opportunity for undergraduate students to perform computational chemistry experiments without the need to purchase expensive software.

"Computer Simulations of Salt Solubility" by Victor M. S. Gil provides an animated, visual interpretation of the different solubilities of related salts based on simple entropy changes associated with dissolution such as configurational disorder and thermal disorder. This animation can help improve students' conceptual understanding of…

Provided is a review of a chemical software package. The package makes possible an instructional technique that is not effective by any other means, namely the ability to view molecular shapes in three dimensions. The program can be used with either IBM or Apple hardware. (RH)

Describes the main features of this database of visual information about the applications, properties, and the chemical reactivity of the elements. The benefits of using this multimedia program include increased safety, decreased material costs, reduced volume of disposal products, and decreased preparation and cleanup time. (DDR)

Reviewed are two computer software packages including "ATOMS-Atomic Structure Display," and "Desktop Molecular Modeller." Discussed are hardware, components, level, cost, strengths, weaknesses, and value for teaching. (CW)

Provides a review of both the Apple and IBM versions of ENZPACK, a software package which is designed to assist in the teaching of enzyme kinetics in courses where this topic is treated in some depth. (TW)

Described is an interactive database of chemical information called "KC? Discoverer: Exploring the Periodic Table." An overview of the program and details of specific functions are given. The uses of this program in teaching undergraduate inorganic chemistry are stressed. (CW)

Described are two reviews of a computer software package: "The Periodic Table Stack," a Hypercard stack that operates on a database of information about the properties and reactions of the elements and designed to help users of Macintosh computers access data found on "KC? Discoverer." Discussed are features of the program and…

Discusses computer simulations for chemistry courses. Reviews a simulation program, "Evaluation of Bonding Theory: The Werner Jorgensen Controversy," and provides information regarding hardware requirements for the program. Presents the idea of an expert system including simulation modules and counselor modules. Describes some chemical examples, a…

Reviewed are two computer software packages: "Introduction to Spectroscopy, IR, NMR & CMR," and "ASYSTANT" (a mathematical and statistical analysis software tool). Discussed are the functions, strengths, weaknesses, hardware requirements, components, level, and cost for each package. (CW)

Reviewed is a computer software package for IBM personal computers. The theoretical background and functions including several examples are discussed. The algorithm used in computation by the program is given. (CW)

Discusses the calculation of free energy in reactions between silicon dioxide and carbon. Describes several computer programs for calculating the free energy minimization and their uses in chemistry classrooms. Lists 16 references. (YP)

Discussed are some uses of computers in chemistry classrooms. Described are: (1) interactive chromatographic analysis software; (2) computer interface for a digital frequency-period-counter-ratio meter and analog interface based on a voltage-to-frequency converter; and (3) use of spectrometer/microcomputer arrangement for teaching atomic theory.…

Reviews two software packages: Graphical Analysis III and Lewis Diagrams. Finds Graphical Analysis III to be a fast and versatile graphing program for high school science classes with access to Apple II microcomputers. Lewis Diagrams is designed to aid in determining Lewis structures of molecules and ions for IBM computers. (MVL)
