Four examples are given of spectra of organophosphorus compounds which show students how the effects of phosphorus are delt with in nmr spectroscopy. (BB)

Presents an undergraduate physical chemistry laboratory experiment describing the measurement of the proton magnetic resonance spectra. (HM)

Describes an experiment for the measurement of the reflectances of dielectric surface. The experiment is analyzed in terms of the Stokes parameters and the Mueller calculus, and Malus law is derived. The experiment also provides an introduction to the properties of real linear polarizers. (Author/GA)

Describes an undergraduate spectroscopy laboratory experiment involving the absorption spectrum of benzene. (SL)

Describes an undergraduate experiment using nmr spectroscopy to study rapid exchange reactions in solutions in which reaction rates are varied by adjusting reagent concentrations. (SL)

Describes how astrophysics can be a do-it-yourself project within a school boy's budget and background, by giving detailed instruction on equipment construction. In addition, this article describes many experiments to undertake, with the equipment, such as determining color temperature, star spectra, chemical composition and others. (BR)

This experiment demonstrates the polarization properties of the transition moment, vibronic activity in an excited state, cyrogenic techniques, crystal site splitting, and the use of mixed crystals. (BB)
