Theory of nuclear magnetic resonance spin-spin coupling constants and nature of the three types of coupling mechanisms contributing to the overall spin-spin coupling constant are reviewed, including carbon-carbon coupling (neither containing a lone pair of electrons) and carbon-nitrogen coupling (one containing a lone pair of electrons).…

Following a delineation of thermoluminescence from a historical perspective and a qualitative description of the process, a treatment of the kinetic process based on a simple model is presented. This treatment model is adequate for the purpose of identifying the essential requirements in instrument design. (BT)

This paper reports an experiment in the teaching of the kinetic molecular theory to nonscience majors by the inquiry method. It allows the student to develop an essentially correct view of gases, liquids, and solids on the atomic or molecular level, and illustrates how one can draw conclusions about the molecular level by simple visual…

Describes the construction of a simple beam model of the hydrogen atom. (SL)

Discusses the energy levels of 3d and 4s electrons. (SL)

Reviews Piagetian concepts, the identification of student cognitive level of development, and chemistry instruction. (SL)

Discusses instructor considerations to be made concerning student cognitive development in preparing and teaching introductory chemistry. (SL)

Discusses seven key concepts in Ausubel's learning theory which function to guide research and teaching. Also discusses concept mapping and Gowins Vee, providing examples of how they are used in chemistry instruction. (JN)

A course for superior freshmen for both science and liberal arts majors that satisfies the freshman chemistry requirement is discussed. It has been taught for six years and utilizes the new math'' which is based on the elementary concept of a set. A syllabus for the two semesters is included. (DF)

Limitations of classical mechanics in understanding molecular properties are discussed. Modifications introduced by quantum mechanics enable the instructor to include and integrate important concepts from thermodynamics, quantum mechanics, spectroscopy, and statistics. (DF)

Described is a method of utilizing the standard ball and stick models, used in demonstrating molecular structure, for building two electron bonding components. Included is the construction of several molecules with word and picture descriptions. (Author/DS)

Presents evidence to support the author's viewpoint that Einstein's General Relativity Theory is related to concepts of chemo-electricity. (CS)

Discusses the learning cycle, a strategy developed by Karplus for incorporating Piaget's concepts into a pragmatic method for use in any classroom. The three facets to this strategy, exploration, invention, and application, are described. Includes an exercise that can be used for high school and college classrooms. (CS)

Details a procedure for accurately calculating the quantum mechanical energies of hydrocarbons using the perturbational molecular orbital (PMO) method, which does not require the use of a computer. (BT)
