Describes a sequence of demonstrations that may serve to initiate and maintain student interest in the development of acid-base theories and bond strength. (GS)

Presents an experimental approach to teaching molecular orbital models. Suggests utilizing photoelectron spectroscopy and molecular orbital theory as complementary approaches to teaching the qualitative concepts basic to molecular orbital theory. (SLH)

Discusses the utility of utilizing Boron-11 in the introductory presentation of nuclear magnetic resonance. (SL)

Presents rudimentary theory for Resonance Raman Spectroscopy and examples of its application. (SL)

Traces the history of the electron theory of the chemical bond. Nineteenth-century ideas on electrical combination, early twentieth-century theories of electrical attraction, and the contribution of G. N. Lewis's shared electron pair are among the topics considered. (JN)

Described is an introduction to the collision theory by arriving at the many degrees of freedom rote constant and showing that the (-Ea/RT) is a special case and corresponds to activation in 2 squared terms on the line of center rate constant, which is found through the use of distributed functions. (Author/DS)

Discussed is the use of instructional aids in chemistry teaching as it relates to mechanisms of learning. (BB)

Discusses the effect of replacing argon gas with krypton gas in electric light bulbs. (RH)

Attributes learning difficulties in introductory chemistry to the thesis that many students have not reached the formal operations level of intellectual development. Cites instances to support this thesis, outlines an instructional procedure to overcome the difficulty, and presents a list of competencies that can be expected of these students. (GS)

Presents excerpts from the scientific writings of Boyle and Newton to demonstrate their use of metaphysical models. (CP)

The operation of teaching associates (TA's) in reference to McGregor's ideas concerning Theory X and Theory Y Management is discussed. (CP)

The purposes of the article are to present some of the simplest facts of theoretical chemistry in a language which is as close as possible to everyday discourse and to introduce one of the basic principles which governs the mechanism in chemical reactions. (Author/CP)

Discusses interactions between electromagnetic radiation and matter, the concept of fluctuating atomic or molecular dipoles, light-scattering, absorption, and photoluminescence. (SL)
