Describes the use of a time-sharing computer and an x-y plotter in a variation of the laboratory exercise on the physical pendulum. (HM)

Described is the transfer function approach which can be applied to a system by measuring the appropriate activation parameters. This approach is conceptually simple and has many mechanistic applications, among which are solvent and structural effects on rates and equilibrium. (Author/DS)

Describes a 9-hour organic chemistry experiment that involves the isolation of (+)-limonene from orange peels and conversion of this product into (-)-carvone. (CS)

Describes an advanced undergraduate laboratory experiment designed to give the senior chemistry student an opportunity to apply several synthetic and purification techniques as well as possibilities for the application of NMR spectroscopy. (CS)

An integral equation for the s-wave bound-state solution is derived and then solved for a square-well potential. It is shown that the scattering solutions continue to exist at negative energies, and when evaluated at the energy of a bound state these solutions do reduce to the bound-state solution.

When examining complex waveforms by examining oscillograms from simple resonant circuits, interpretation problems occur. These problematic oscillograms are explainable by recognizing that the typical resonant filters pass significant amounts of several harmonics adjacent to the one intended. Adjacent harmonics effects are computed; resulting…

Briefly refers to the history, physiological background, and adaptive implications of two theories concerning the limits of sensory discrimination. An experiment is described, suitable for college and high school students, which investigates the validity of the two theories. (CS)

Describes an apparatus that offers a very lucid demonstration of Poisson statistics as applied to electrical currents, and the manner in which such statistics account for shot noise when applied to macroscopic currents. The experiment described is intended for undergraduate physics students. (HM)
