Describes a polymerization reactor engineering course offered at Michigan Technological University which focuses on the design and operation of industrial polymerization reactors to achieve a desired degree of polymerization and molecular weight distribution. Provides a list of the course topics and assigned readings. (TW)

Describes a classroom experiment designed to teach students the fundamentals underlying the normal coordinate analysis procedure of a polyatomic molecule. Uses a reverse procedure from traditional experiments of this type by providing the values for the force field and working backwards. (TW)

Describes an inexpensive molecular model which is small enough to manipulate and large enough to be seen by large audiences. Discusses models of atoms and double and triple bonds. (JM)

Thirteen computer/calculator programs (available from authors) are described. These include: representation of molecules as 3-D models; animated 3-D graphical display of line drawings of molecules; principles of Fourier-transform nuclear magnetic resonance; tutorial program for pH calculation; balancing chemical reactions using a hand-held…

Two demonstrations are described: (1) a sunset effect using a gooseneck lamp and 20 sheets of paper and (2) the preparation and determination of structural features of dimethyl sulfoxide (DMSO) by infrared spectroscopy. (SK)

Describes a Simple Huckel Molecular Orbital (SHMO) computer program written in BASIC and suitable for use on a variety of common microcomputers. (SK)

Discusses when the writing of chemical formula and equations can be introduced in the school science curriculum. Also presents ways in which formulae and equations learning can be aided and some examples for balancing and interpreting equations. (HM)

Described is a method that can be used to obtain molecular or atomic term symbols. Several examples accompany an explanation of the method. (CW)

Finds that a logical application of the simple rules of the molecular orbital bonding theory for diatomic molecules predicted the existence of three spin isomers of the oxygen molecule: one triplet form with two unpaired electrons and two singlet forms with all electrons paired. (MVL)

Describes an experimental procedure to acquaint inorganic chemistry students with stereochemical concepts using tris-(2,3-butanediamine)cobalt(III). Notes two isomeric forms exist and both form metal chelates. Separation is accomplished by chromatography and analysis is by NMR and infrared spectroscopy. Provides spectra of isomers. (MVL)

A decision tree which can be used to help students determine the proper stereochemical relationship between two isomeric structures is presented. The proper use of this chart is discussed. (CW)

Presented are three demonstrations: "The Construction and Use of Commercial Voltaic Cell Displays in Freshman Chemistry"; Dramatizing Isotopes: Deuterated Ice Cubes Sink"; and "A Simple Apparatus to Demonstrate Differing Gas Diffusion Rates (Graham's Law)." Materials, procedures, and safety considerations are discussed. (CW)

Describes two simple procedures allowing students to experiment with living membranes and to relate their results to fundamental membrane structure. Provides instructions for determining the effects of temperature and organic solvent stress on cellular membranes, and spectrophotometric analysis. (RT)

Provides a brief introduction with some definitions and properties of Fourier transforms. Shows relations, ways of understanding the mathematics, and applications. Notes proofs are not included but references are given. First of three part series. (MVL)

Described is the application of microcomputers to predict reaction rates based on theoretical atomic and molecular properties taught in undergraduate physical chemistry. Listed is the BASIC program which computes the partition functions for any specific bimolecular reactants. These functions are then used to calculate the pre-exponential factor of…
