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

Reviews experiments performed in a mobile spectroscopy laboratory. (SL)

Procedures and discussion of an experiment to be used in an undergraduate course in spectroscopy are presented. The experiment involves the measurement of the absorption spectrum of sodium vapor. (DT)

Describes a simple method, the Edser-Butler methods, for calibrating the Fabry-Pevot fringes seen in the focal plane of a spectrograph. (GA)

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.…

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)

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)

Describes the results of a study on the use of computer-simulated chemistry experiments. Four different simulated experiments were compared with four comparable laboratory performed experiments. Concludes that simulation has better results and is a good teaching procedure. (GA)

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)

Describes an advanced analytical chemistry laboratory experiment developed for the determination of the performance parameters of a spectrophotometer. Among the parameters are the baseline linearity with wavelength, wavelength accuracy and respectability, stray light, noise level and pen response time. (HM)
