Surveys the research of scientists like Joule, Kelvin, Maxwell, Clausius, and Boltzmann as it comments on the basic conceptual issues involved in the development of a more precise kinetic theory and the idea of a kinetic atom. (Author/SK)

Presented are forms of harmonic oscillator attraction and Coulomb wave functions which can be explicitly constructed and which lead to numerical results for the energy eigenvalues and eigenfunctions of the atomic system. The Schrodinger equation and its solution and specific cases of muonic atoms illustrating numerical calculations are included.…

Describes features of a new type of chemical database which provides the ability to search for substances sharing particular structural characteristics. Search concepts are examined in detail, and menu selection of "screens," system commands, and interpretation of results (which appear in the form of chemical bond structures) are…

It is shown that exact pseudopotentials for excited states of hydrogen atoms can be derived. A very simple, novel application of pseudopotential method which displays vividly some of its limitations is presented. (Author/GA)

Develops the concept of oscillatory v dissipative limits as it applies to electronic excited state processes in molecular systems. Main emphasis is placed on the radiative and nonradiative dynamics of the excited state of a molecule prepared by interaction with light or some other excitation source. (BT)

This is part III of an explanation of the influence and development of quantum mechanical ideas as applied to inorganic complexes. (Author/SA)

Discusses a comparison of the relative effects on the stomach of a strong acid, hydrochloric acid, and a weak acid, aspirin. Also discusses molecular geometrics using the Valence Shell Electron Repulsion Theory. (MLH)

Describes an advanced inorganic chemistry experiment in which students prepare two coordination compounds and study their stereochemistry using infrared spectroscopy. (MLH)

Describes an activity in which students apply the scientific method as they explore each step of crystal growing. Students select variables, record daily observations, and participate in discussions about the differences in crystal formation. Crystal recipe and procedures are provided. (DDR)

Described is research conducted on cluster-assembled matter. The differing character of these arrangements of matter are discussed. Methods used to produce clusters are reviewed. (CW)

Discussed is the preparation of synthetic brochantite from solution and a thermogravimetric-differential thermal analysis study of the thermal decomposition of this compound. Other analyses included are chemical analysis and IR spectroscopy. Experimental procedures and results are presented. (CW)

Outlined is a method for collecting and cutting oriented samples for microstructural analysis including handling the samples in the laboratory, cutting and orienting chips parallel to the motion plane, and cutting and orienting chips normal to Le and foliation. (CW)

Academia and industry both have an interest in the economic aspects of drug development, including the rising cost of new drug discovery, the decrease in the effective patent life of new drugs as the drug improvement process lengthens, and the impact of drug-related litigation. (MLW)

Reports on the human immunodeficiency virus which causes disease that culminates in the Acquired Immunodeficiency Syndrome (AIDS). States that the key to prolonging life and health is early detection of the infection which usually occurs years before symptoms emerge. (RT)

A method designed to facilitate prediction of mechanism and products by developing critical thinking skills and reducing memorization is presented. The mechanistic disc method requiring students to utilize their understanding of charge stabilization, structural organic chemistry, and the fundamental mechanisms of aliphatic substitution and…
