Describes an experiment designed to familiarize students with the operation of a precision spectrophotometer, the effects of changes in operating variables, and the characteristics of such components as sources and detectors. (SLH)

Presents an experiment involving the identification of FD&C dyes by visible spectroscopy. (SL)

A computer program which simulates an interstellar gas and dust cloud has been used to study Kirchhoff's laws of spectral analysis in introductory astronomy courses. The model parameters can be varied to stimulate various effects observed in actual clouds. Students are given exercises to use the program in a manner similar to a lab experiment.…

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 the use of nuclear magnetic resonance (NMR) spectroscopy to study a three-component system and the technique by which to define a ternary phase diagram. (CP)

Experimental procedures for studying enzyme activity using a Spectronic 20 spectrophotometer are described. The experiments demonstrate the effect of pH, temperature, and inhibitors on enzyme activity and allow the determination of Km, Vmax, and Kcat. These procedures are designed for teaching large lower-level biochemistry classes. (MR)

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)

The author believes that one of the best ways of educating the student of contemporary and future technology is to use modern devices, instruments, and techniques in an up-to-date college laboratory. Experiments which motivate and which are of interest to the student, the professor, and industry should be used extensively. (Author/TS)

A laboratory experiment is described which presents some molecular parameters of iodine molecule by studying iodine spectrum. Points out this experiment can be conducted by sixth form students in high school laboratories. (PS)
