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…

Background information, procedures used, and typical results obtained are provided for an experiment (based on the potassium bromide pressed-pellet method) involving the infrared spectroscopy of deuterated compounds. Deuteration refers to deuterium-hydrogen exchange at active hydrogen sites in the molecule. (JN)

Discusses problems and prospects in: (1) multielement atomic adsorption spectroscopy (AAS); (2) inductively coupled plasma (ICP) atomic emission; and (3) other aspects of atomic spectrometry. (JN)

Explains the physical principles which result in various colors of the sky. Topics addressed include: blueness, mystical properties of water vapor, ozone, fluctuation theory of scattering, variation of purity and brightness, and red sunsets and sunrises. (DH)

Describes relatively simple nuclear magnetic resonance (NMR) experiments that demonstrate unexpected results of the deceptively simple and deceptively complex types. Background information, experimental procedures, and typical results obtained are included. (JN)

Describes a physics experiment in single and multiple slit diffraction and interference phenomena that illustrates the existence of diffraction gratings in many common objects. (MLH)

Most inorganic chemistry textbooks present the determination of spectroscopic terms obtained from a given electronic configuration by a method which requires explicitly writing down all microstates. A method is provided and discussed in which tabulating all possible microstates is not required. (JN)

Describes a PASCAL computer program which provides interactive analysis and display of high-resolution nuclear magnetic resonance (NMR) spectra from spin one-half nuclei using a hard-copy or monitor. Includes general and theoretical program descriptions, program capability, and examples of its use. (Source for program/documentation is included.)…

Discusses some lesser known examples of atomic phenomena to illustrate to students that the old quantum theory in its simplest (Bohr) form is not an antiquity but can still make an important contribution to understanding such phenomena. Topics include hydrogenic/non-hydrogenic spectra and atoms in strong electric and magnetic fields. (Author/JN)

Describes a set of undergraduate laboratory experiments which provide experience in deuteration and derivatization procedures applied to infrared spectroscopy. Basic skills in vacuum-line technique are also taught while measuring infrared spectra of deuterated solid samples and demonstrating the value of derivatization as an aid to interpreting…

Highlights procedures and results of an experiment using atomic absorption spectroscope to illustrate a fundamental chemical concept. The experiment demonstrates the dependence of the solubility product of lead sulfate on ionic strength in the presence of a slight excess of anion. (Author/JN)

The monochromaticity, directionality, and intensity of laser light make possible spectroscopic investigations of previously unimagined precision. Several of these investigations and their applications are discussed. (Author/JN)
