Described are the elementary principles of Fourier transform spectroscopy and typical experimental results obtained with a modified Michelson interferometer. (RH)

Described is a device that can be set up on a bench with inexpensive apparatus. The device performs in non-coherent white light according to the laws of geometrical optics. (RH)

Describes a low-cost ($120) device which eliminates plasma lines in Raman spectra. The device consists of two prisms and two mirrors which are held in a symmetrical relationship to one another so that a particular position will allow only one wavelength to pass through on a given axis. (JN)

Presented is an introduction to the interpretation of electron spin resonance spectra of organic radicals. The article is written for undergraduate college students. (RH)

Outlined is a procedure for analyzing the ground electronic state of the iodine molecule by using information provided by "hot" bands, observed in the absorption spectrum of iodine vapor. (RH)

Outlines how the radiative properties of a surface can be tailored so as to be favorable for efficient utilization of energy. The radiative properties of concern are transmittance, reflectance, absorptance, and emittance. (JN)

A previous part (Analytical Chemistry; v57 n9 p1057A) discussed the theoretical aspects of diode ultraviolet-visual (UV-VIS) spectroscopy. This part describes the applications of diode arrays in analytical chemistry, also considering spectroelectrochemistry, high performance liquid chromatography (HPLC), HPLC data processing, stopped flow, and…

Discusses polymerization evaluation by spectrophotometric measurements by considering: (1) association degrees and molar absorptivities; (2) association degrees and equilibrium constants; and (3) absorbance and equilibrium constants. (JN)

Presents a short set of carbon-13 nuclear magnetic resonance (NMR) tables. These tables not only serve pedagogic purposes but also allow students to do calculations rapidly and with acceptable accuracy for a wide variety of compounds. (JN)

Fourier transform nuclear magnetic resonance (NMR) is a new spectroscopic technique that is often omitted from undergraduate curricula because of lack of instructional materials. Therefore, information is provided to introduce students to the technique of data collection and transformation into the frequency domain. (JN)

Reviews various spectroscopic techniques currently used to analyze real physical surfaces that bound two actual phases. Problems inherent in analyzing these surfaces and possible approaches that may be taken are considered. (JN)

This article describes a practical experiment for teaching basic spectroscopic techniques to introduce the topic of protein conformational change to students in the field of molecular biology, biochemistry, or structural biology. The spectroscopic methods employed in the experiment are absorbance, for protein concentration measurements, and…

A qualitative description of the color-change problem, which will assist in rationalizing the change in color of marbles after grinding them using a simple physical picture and the qualitative dependence of diffuse reflectance on particle size is presented. Different approaches are discussed but it is seen that the interpretation of nanoparticles…
