Gilbert, George L., Ed. – Journal of Chemical Education, 1989
Discusses three broad classes of magnetic behavior: diamagnetic, paramagnetic, and ferromagnetic. Presents a simple lecture demonstration using an overhead projector to synthesize triiron tetraoxide and to show its interaction with a magnetic field and comparing it to a paramagnetic material. (MVL)
Descriptors: Chemical Bonding, Chemical Reactions, Chemistry, College Science
Peer reviewed Peer reviewed
Magyar, Elaine; Magyar, James G. – Journal of Chemical Education, 1989
Investigates the four week chemistry program in a summer program in science and mathematics. Identifies weekly topics for the program: (1) color and visible spectroscopy; (2) UV spectroscopy, fluorescence, and chemiluminescence; (3) IR and NMR spectroscopy; and (4) lists 12 individual projects. (MVL)

Etzel, A. J.; And Others – Journal of Chemical Education, 1986
Describes an experiment in which stretching a rubber band can be used to compare the statistical theory of rubber elasticity with its continuum mechanics counterpart. Employs the use of the equation of the state of rubber elasticity and the Mooney-Rivlin equation. (TW)

Sayed, Yousry; And Others – Journal of Chemical Education, 1989
Describes several common synthetic organic transformations involving alkenes, alcohols, alkyl halides, and ketones. Includes concepts on kinetic versus thermodynamic control of reaction, rearrangement of a secondary carbocation to a tertiary cation, and the effect of the size of the base on orientation during elimination. (MVL)

Chesick, John P. – Journal of Chemical Education, 1989
Uses simple pulse NMR experiments to discuss Fourier transforms. Studies the generation of spin echoes used in the imaging procedure. Shows that pulse NMR experiments give signals that are additions of sinusoids of differing amplitudes, frequencies, and phases. (MVL)
Descriptors: Atomic Structure, Chemical Analysis, Chemistry, College Science

Tan, Barrie; Soderstrom, David N. – Journal of Chemical Education, 1989
Explores the structural behavior of polyenic pi systems such as isomerization and conjugation. Uses the simultaneous spectrophotometric analysis of a beta-carotene and lycopene mixture. Presents an empirical method to determine the number of double bonds in the polyenic carotenoid. (MVL)

DeVore, T. C.; Gallaher, T. N. – Journal of Chemical Education, 1986
Describes a physical chemistry experiment which uses spectroscopy to measure the heat of formation of Na2SiF6. Discusses the opportunities for students to see the use of a familiar instrument in an unfamiliar application, emphasizing that there are often many ways to attack problems in science. (TW)
