Describes a program in which a community college offered its instructional and physical resources to local gifted and talented high school students and their teachers. Students, accompanied by their teachers, performed research on the college campus. Indicates the importance of teachers being on campus with students. (SK)

Gas phase acidity data shown are offered to writers of elementary organic chemistry texts for replacement of the aqueous phase data that are universally used. Relative acidities in the gas phase are controlled virtually exclusively by enthalpic factors. Structural-energetic explanations of acidic trends can therefore be used. (SK)

Summarizes a survey on undergraduate research in chemistry from 1920-1976. Reviews the role and importance of factors such as faculty compensation and student ability on such research. Includes raw data for schools in the survey. (SK)

Describes the use of the Gaussian 70 computer programs to carry out quantum chemical calculations, including single calculations, geometry, optimization, and potential surface scans. Includes a summary of student activities and benefits for students in an honors freshman chemistry course. (SK)

Presents discussion on: (1) computer assisted synthesis in industry and academia; (2) computer applications to teaching organic synthesis; (3) a computer program (ORGSYN) incorporating reactions to synthesize aliphatic compounds; and (4) the design of a computer program as a heuristic device in an introductory organic course. (SK)

Provides instructions and a list of materials needed to demonstrate: (1) a model of the quantum mechanical atom; (2) principles involved in metal corrosion and in the prevention of this destructive process by electrochemical means; and (3) a Thermit reaction, modified to make it more dramatic and interesting for students. (SK)

Discusses whether chemistry should be taught using a purely descriptive approach or using the current "principles" approach. Considers what sort of background should be provided given the uses students are most apt to make of their general chemistry training. (SK)

Describes some impurity-related optical properties of semiconductors, with special emphasis on the luminescence of zinc sulfide (ZnS). Presents and interprets five experiments using a ZnS screen, ultraviolet lamp, transparent Dewar liquid nitrogen, and a helium/neon gas base. Includes application of luminescence measurements to archaeology. (SK)

Describes an experiment providing an experimental introduction to vibrational spectroscopy and experience in using an elementary vacuum line. The experiment, using a gas cell charged with methanol, is completed in a three-hour laboratory period and is directed toward understanding vibrational spectroscopy rather than the diagnostic value of the…

Presents background information, materials needed, and experimental procedures to study enzymes dependent on pyridine nucleotide coenzymes (NAD/NADH). The experiments, suitable for advanced organic or biochemistry courses, require approximately 10-15 hours to complete. (SK)

Describes an experiment to analyze commercial analgesic preparations (pain relievers) by silica gel thin layer chromatography, followed by preparative (thick) layer chromatographic separation and spectroscopic analysis. Key difference from similar experiments is that students are responsible for devising suitable solvent systems for the thin layer…

Describes a three-hour liquid chromatography experiment involving rapid separation of colored compounds in glass columns packed with a nonpolar absorbent. Includes apparatus design, sample preparation, experimental procedures, and advantages for this determination. (SK)

Lists commercially available audiovisual materials by subject area. Includes title, producer (addresses given), catalog number, format (film, filmstrip, cassette, slides), and prices. Subject areas include: elements; equilibrium; gases; laboratory techniques and experiments; general chemistry; introductory materials (including mathematics); and…

Presents general and specific guidelines for handling carcinogens. Additional topics include: definition of potential occupational carcinogens; classification of carcinogens; inventory requirements; signs and labels for materials and laboratories; decontamination and disposal procedures; medical surveillance for employees working with controlled…

Describes developments in the stereochemistry of coordination compounds. Includes chemical structures and chemical reactions of selected compounds. (JN)
