Selected infrared laser chemistry topics are discussed including carbon dioxide lasers, infrared quanta and molecules, laser-induced chemistry, structural isomerization (laser purification, sensitized reactions, and dielectric breakdown), and fundamental principles of laser isotope separation, focusing on uranium isotope separation. (JN)

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).…

Examines Toledo Chemistry Placement Examination results for 3,227 students entering University of Toledo during 1977-1980, focusing on general trends developed during the period and on chemical and mathematical concepts, identifying some of the misconceptions high school students bring to their college studies. (Author/JN)

Provides background information and problems with the formaldehyde clock reaction, including comparisons of experimental clock times reported in the literature and conditions for the reliable use of the formaldehyde clock based on a method discussed. (JN)

Outlines and discusses procedures for the preparation of lucigenin, a powerfully chemiluminescent compound. Major techniques (requiring three 4-hour sessions) involving nucleophilic and electrophilic aromatic substitution, nucleophilic aliphatic substitution, reductive coupling, and oxidation reactions include steam distillation, decolorization…

Presents background information, materials, calculations, and laboratory procedures for a physical chemistry experiment focused on the thermodynamics of a galvanic cell. (JN)

Describes the rationale for and implementation, content, objectives, and format of an undergraduate toxicology course. Includes criteria required to offer such a course. (SK)

Describes a series of easily constructed octahedra having surface facets so that each displays one of the cubic point group symmetries. These may be used simultaneously with other kinds of models to provide within each point group several objects for comparison and study. (Author/SK)

Illustrates and outlines steps for constructing models of twin octahedrons and a rhombohedron. (SK)

A flow chart is used to illustrate analytical chemistry as a component of a problem-solving process. Beginning with a problem, the flow chart proceeds to the question, experimental design, experiments, data treatment, answer, and solution. Another flow chart is used to expand on experimental design. (Author/SK)

To remedy certain deficiencies, an instrument analysis course was reorganized into six one-unit modules: optical spectroscopy, magnetic resonance, separations, electrochemistry, radiochemistry, and computers and interfacing. Selected aspects of the course are discussed. (SK)

Compares performance of first-year general chemistry college students from 32 institutions with performance of Advanced Placement (AP) Chemistry Candidates in 1978 to provide a concurrent validity measure of the multiple-choice section of the AP chemistry examination. Average AP candidates scored significantly higher than average college students.…

Describes a non-credit, remedial mathematics course for introductory chemistry students taught before the beginning of a regular semester. Recommendations to take the course, to review mathematics, or indicating that further review is not necessary are based on the results of a test mailed to students before the beginning of the semester. (SK)

Strategies for incorporating a calculator made within FORTRAN programs and a Response Analysis Scheme during interactive sessions are described highlighting salient features of the programs. (Author/SK)

A physical chemistry computer program with seven subprograms (available from the author) was developed to present student questions, evaluate mathematical expressions (calculator mode), retrieve tables, and refresh output on the terminal. Criteria for easily adding new questions are listed and sample output included. (SK)
