Describes an undergraduate laboratory experiment that demonstrates the value of shift reagent use in producing a first-order spectrum of trans-retinol. (CS)

Provides explanations for the variations in appearance of spectra taken at different pressures and cell lengths. (CS)

Provides a simple method for finding the values of the total angular momentum J for configurations of equivalent electrons in jj coupling. Shows how a knowledge of both the LS and jj terms can contribute to the students' understanding of the role of different representations in quantum mechanics. (Author/GS)

Briefly discusses new instrumentation in the field of analytical chemistry. Advances in liquid chromatography, photoacoustic spectroscopy, the use of lasers, and mass spectrometry are also discussed. (CS)

Considered are the main elements of computational chemistry problems and how these elements can be used to formulate the problems mathematically. Techniques that are useful in devising an appropriate solution are also considered. (Author/TG)

Introduces luminescence by characterizing phosphors, describing phosphor phenomena, presenting a configurational coordinate model of characteristic luminescence, and describing some commercial applications of phosphors. (CS)

Presents a combined knowledge of both the chemistry and physics of amorphous conductors in an attempt to understand these unconventional solids. (CS)

Diagrams and tables supplement textual information regarding the structure of ScNbo-4 and its observed and calculated d-values; excitation and emission spectra and cell constants for the ScTa(1-x)NB(x)O(4) system. (CS)

Summarizes opening remarks made at the sixty-third meeting of the Chemical Institute of Canada in a panel discussion on the subject of teaching electrochemistry. (CS)

Presents an annotated list of 23 audiovisual materials currently available for use in teaching of chemical literature. (JN)

The facility index of a test item is the percentage of testees choosing the correct response. A common curriculum model presents process and content as two dimensions of the difficulty of an educational task. Wheeler suggested a third dimension: precision. This three-dimensional model is applied to chemistry education. (BW)

Discusses methods for cultivating growth in understanding science, including the development of an experiential understanding of the scientific method, the fostering of a cultural understanding of scientific growth, and the sociological understanding of scientific implications. (CS)

Describes a system of heuristics for problem solving and instructional methods for presenting it to secondary school students. (CS)

Reviews properties, geologic occurrences, availability to plants, and cycles of the element selenium. (CS)

Reports methods for identifying carcinogens and suspected carcinogens in the undergraduate laboratory and makes recommendations for their elimination or control. (CS)
