Described are infrared windows made from Tupperware and polyethylene coffee can lids that provide acceptable spectra for low-frequency infrared. (RH)

Described is a quick, easy, and cheap, but effective method of obtaining infrared spectra of solids and nonvolatile liquids by Fourier transform infrared spectroscopy. The technique uses tissue paper as a support matrix. (RH)

Described is an alternative method to infrared spectroscopy for the quantification of xylene mixtures. The method employs nuclear magnetic resonance spectroscopy. (RH)

This paper explores how Fourier Transform (FT) mimics spectral transformation, how this property can be exploited to advantage in spectroscopy, and how the FT can be used in data treatment. A table displays a number of important FT serial/spectral pairs related by Fourier Transformations. A bibliography and listing of computer software related to…

Described is a laboratory exercise that uses nuclear magnetic resonance to monitor enantiomeric excess in asymmetric reductions. The laboratory exercise has been used successfully with undergraduate organic chemistry students. (RH)

Reports results of a survey in which 110 universities were selected to respond to questions regarding approximate age and cost of the instruments used in three major areas: separations, spectroscopy, and electroanalysis. Respondents (N=41) also indicated which pieces of equipment were used in undergraduate courses or were used for research. (CS)

Addresses solution nonmetal determinations on a fundamental level. Characterizes research in this area of chemical instrumentation. Discusses the fundamental limitations of nonmetal atomic spectrometry, the status of nonmetals and atomic spectroscopic techniques, and current directions in solution nonmetal determinations. (CW)

Describes the use of infrared and atomic absorption spectrometry in an introductory chemical oceanography course to introduce students to carbonate mineralogy by having them determine both the crystal structure and the magnesium content of seashells that they have collected. (Author/JN)

Discusses the history and development of Plasma Desorption Mass Spectrometry to determine molecular weights and structures of proteins and polymers. Outlines theory, instrumentation, and sample preparation commonly used. Gives several examples of resulting spectra. (ML)
