This new WebWare combines instructional text and Jmol interactive, animated illustrations that help students visualize the mechanism. It is concluded that by animating the fluxional behavior of a simple model for chiral metal catalyst Sn(amidinate)[subscript 2], in which axial/equatorial exchange within the amidinate rings occurs through a Berry…

Tips that laboratory researchers and beginning graduate students can use to safeguard against explosion hazard with emphasis on clear illustrations of molecular structure are discussed. Those working with hazardous materials must proceed cautiously and may want to consider alternative and synthetic routes.

The National Science Education Standards (NRC 1996) recognize the efficacy of teaching science within the context of history, emphasizing the evolution of concepts, models, and theories. By studying science in a historical context, students view themselves less as spectators and more as participants in this human quest for truth and understanding.…

Discusses using the historical account of the concept of the tetrahedral carbon atom as a study in scientific methodology. (MLH)

Describes an undergraduate chemistry experiment in which an atomic absorption spectrophotometer is used for recording flame emission spectra of the diatomic carbon molecule. (MLH)

Includes a discussion of the structure of some molecules and the design of an experiment to replace CHEM Study Experiment 7. (GS)

Describes an experiment which monitors the population of the lowest triplet state by directly observing phosphorescence intensity as a function of time. Reviews the theory concerning triplet state lifetimes, describes the experimental apparatus and procedure, and presents the method and examples of data analysis. (GS)

A brief introduction to the periodic table of the elements is presented. The periodic relationships are demonstrated through the use of seven tables which include a breakdown of the periodic table by groups or families, valence ring electron populations by period, electronic configurations of the elements, electron configurations of the elements…

This is the second of several papers which attempts to introduce group representation theory to students of molecular or solid-state physics in as intuitive and simple a fashion as possible. (Author/BB)

This purpose of this article is to explain, in simple terms, the difficulty students have in a British sixthform course in proceeding from X-ray photograph to molecular structure. (HM)

Describes the components and the molecular structures of soaps and detergents and the way they work. (GA)
