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)

Describes new apparatus and equipment including balances, spectrophotometers, gas chromatographs, pH meters, calculators and temperature controllers. (GS)

Based on instructional experiences at Charles County Community College, Maryland, this report examines the pedagogical advantage of teaching atomic absorption (AA) spectroscopy with an AA spectrophotometer that is equipped with a microprocessor and video output mechanism. The report first discusses the growing importance of AA spectroscopy in…

Instructions accompanied by illustrations for building a low-cost demonstration spectroscope are presented. Materials and tools are pictured and labeled. Cost is estimated at five dollars (in 1980) and twelve hours of work are required to build the spectroscope. (SA)

Describes an undergraduate experiment that provides instruction in nuclear magnetic resonance (NMR) spectroscopy, reaction rates, and the application of mathematical procedures. (MLH)

A new scale is suggested, with the objective of simplifying relationships between the various scales and units used in spectroscopy. Although there are certain drawbacks to such a scale, it is hoped that the suggestion will stimulate discussion on the relevance of the many scales and units that are used. (Author/BB)

Surveys new laser techniques and a variety of spectroscopic experiments that can be used to detect, measure and study very small numbers of atoms on molecules. The range of applicability of these techniques is also included. (HM)

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

Describes a procedure for modifying an interferometer which compensates for distortions when making interferograms. (SL)

Describes two demonstrations for use in college chemistry classes. Includes "Spectroscopy in Large Lecture Halls" and "The Endothermic Dissolution of Ammonium Nitrate." Gives materials lists and procedures as well as a discussion of the results. (CW)

Discusses the factors affecting the behavior of a spectral function. Lists some important properties of Fourier transform (FT) pairs that are helpful when using the FT. Notes that these properties of the mathematical formulation have identical counterparts in the physical behavior of FT systems. (TW)

Discusses the properties of laser light, reviews types of lasers, presents operating principles, and considers mechanical aspects of laser light production. Applications reviewed include spectroscopy, photochemical reaction initiation, and investigation of biological processes involving porphyrins. (JM)

Describes an experiment for recording two individual spectrophotometer response curves. The two curves are directly related to the power of transmitted beams that pass through a solvent and solution. An absorption spectrum of the solution can be constructed from the calculated rations of the curves as a function of wavelength. (JN)

Background information, procedures used, and typical results obtained are provided for an experiment that examines the ability of nuclear magnetic resonance (NMR) to distinguish between structural isomers via resonance multiplicities and chemical shifts. Reasons for incorporating the experiment into organic, analytical, or physical chemistry…
