Describes the application of a computer program designed to produce a formula determination simultaneously accounting for both elemental composition and probable isotopic species for a measured ion mass. (SLH)

Emphasizes the simplicity and elegance of early discoveries related to the hydrogen spectrum and provides an elementary experimental basis of quantum theory based on a "numbers game" which can be played by students. (Author/GS)

This project developed a mobile spectroscopy laboratory, a truck equipped with scientific instruments which can be moved from school to school to provide hands-on experience with instruments normally too expensive for a small school to purchase. A summer conference trained the on-campus participant faculty in the use of the truck-laboratory as…

Presents several demonstrations in spectroscopy. (RH)

Describes a teaching model that consists of a plywood box containing mechanisms that instruct the student about the technical aspects of an infrared spectrophotometer and how a spectrum is generated. (MLH)

Describes an experiment which quantitatively determines glucose by a spectrophotometric measurement of the colored complex formed between glucose and an amine. (MLH)

Describes the use of atomic spectra that are excited in inductively coupled plasmas for the simultaneous or sequential determination of the elements at all concentration levels. (HM)

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 the development of the ion scattering spectrometry (ISS) analytical instruments. (SL)

Provides an evaluation of the Macbeth Student Spectrophotometer (MSS-100) and describes the use of Slinky toys to demonstrate harmonic motion. (SL)

Describes the mobile spectrosocopy laboratory program operated by the Department of Chemistry, University of Arkansas, which gives small college chemistry departments access to high cost spectrographic instruments mounted in a mobile van. (SL)

Discusses the use of the FT-IR spectrometer in analyses that were previously avoided. Examines some of the applications of this spectroscopy with aqueous solutions, circular internal reflection, samples with low transmission, diffuse reflectance, infrared emission, and the infrared microscope. (TW)

Describes an undergraduate organic chemistry experiment (requiring three/four 3-hour laboratory sessions) involving a four-stage synthesis of 1-phenyl-1,2,3,4-tetrahydroisoquinolines via the Pictet-Spengler route. In addition, the experiment allows students to study the spectra and properties of aklaloid-like materials while completing several…

Examines techniques used to make ultrasensitive spectroscopic measurements. They include excitation, thermal lens, photo acoustic, and ionization spectroscopies. Guidelines and methods are provided for each technique; common uses and applications are explained. (DH)

Describes a set of experiments (for senior-level biochemistry students) which permit evaluation and estimation of rate and equilibrium constants involving an intermediate in the alpha-chymotrypsin mediated hydrolysis of ortho-hydroxy-alpha-toluenesulfonic acid (I). The only equipment required for the experiments is a well-thermostated double beam…
