Describes an experiment for recording two individual spectrophotometer response curves. The two curves are directly related to the power of transmitted beams that pass through a solvent and solution. An absorption spectrum of the solution can be constructed from the calculated rations of the curves as a function of wavelength. (JN)

Presents an internally consistent set of 63 substituent constants developed for use with the Schoolery Relationship to predict the chemical shifts of methylene protons of acyclic compounds. Chemical shift data used in deriving the constants were taken mainly from primary sources of HNMR (nuclear magnetic resonance) spectra. (JN)

An experiment which measures the steady-state fluorescence of pyrene (the donor) in the presence of varying concentrations of acridine orange (the acceptor) in ethyline glycol solutions is described. Background information, equipment needed, and procedures used are included. (JN)

Describes an experiment in which the kinetics of dimerization of nitrosamine induced by a flash of light is measured. The experiment can be performed with a commercial ultraviolet-VIS spetrophotometer with easy to make modifications. The experiment demonstrates a flash photolysis system not always available in university chemistry laboratories.…

Outlines a cooperative effort in Iowa to eliminate dangerous or unwanted chemicals from school science storerooms. Also reviews the Council of State Science Supervisor's safety program and discusses how to prevent cuts and punctures from jagged glass tubing. (JN)

Presents an appendix to the Committee on Professional Training (CPT) of the Division of Chemical Health and Safety of the American Chemical Society. The information is applicable to chemical health and safety policies and practices within the chemistry department of an academic institution. Includes lists of references with safety information. (JN)

Examines the current debate concerning molecular structure, providing an overall assessment of the debate, discussing the development and relationship of successive concepts of molecular structure, and considering what students should be taught about molecular structure and quantum mechanics. Also addresses the tension between continuity and…

Describes a convenient procedure, the Odd-Even Rule, for predicting the allowedness of forbiddenness of ground-state, pericyclic reactions. The rule is applied to a number of specific reactions. In contrast to the Woodward-Hoffman approach, the application to each reaction is always the same. (JN)

Presents a descriptive overview of recent achievements in atomic structure to provide instructors with the background necessary to enhance their classroom presentations. Topics considered include hadrons, quarks, leptons, forces, and the unified fields theory. (JN)

Suggesting that descriptive chemistry is basic to basic chemical literacy, offers examples of descriptive chemistry problems (with answers) based on inexpensive, short, safe, striking, and simple lecture experiments. Issues related to the teaching of descriptive chemistry are also addressed. (JN)

Several interesting and important examples of kinetic stability and kinetic control in organic systems are discussed. Audiovisual aids, lecture demonstrations, and laboratory activities that can be used to convey the material in a clear and stimulating fashion are also described. (JN)

Chemistry students selected a main group of the periodic table, researched the group, and then presented a 70-minute lecture on the group; conducted two lecture demonstrations; and performed two laboratory experiments. This was done to determine what descriptive chemistry should be included in a new sophomore-level inorganic chemistry course. (JN)

Discusses some of the latest developments in the chemistry of printed circuit substrates. Topics considered include soldering, dicy (a catalyst), Kevlar (an aramid polymer fiber), maleimide copolymers, and flexible circuits. (JN)

Describes a program designed to prepare students to work upon graduation in the industrial chemical field as chief chemists in production plants; in analytical laboratories; or in sales, management, or public relations within chemical firms. Also describes industry-college relationship established to achieve program objectives. (JN)

Describes the development of an interdisciplinary chemistry-business major (University of Wisconcin-Eau Claire) designed to prepare students for nonlaboratory careers in the chemical industry. Provides information on courses offered, sample program sequence, and description of a novel undergraduate industrial chemistry course. (JN)
