Describes an experiment simulating a real-life structure elucidation problem through isolation, characterization, and chemical transformation of an "unknown," naturally occurring monoterpene, with extensive use being made of spectroscopy and aided by biogenetic considerations. Information given to students, procedures, results, and discussion of…

Describes a series of experiments (intended to approximate the research experience) investigating the reaction of ferrocenylmethylation with aniline. Students carry out reactions in nitrogen atmosphere, identify products by nuclear magnetic resonance spectroscopy and propose mechanisms and structures for reactions. Gives procedures for each…

Presents a procedure for an integrated first year chemistry laboratory class which provides an effective and colorful procedure to develop manipulative skills in synthesis and purification. Uses thin layer chromatography and NMR spectroscopy in the determination. Provides Rf values and representative NMR spectra. (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)

Discusses the importance of ion chromatography in separating and measuring anions. The principles of ion exchange are presented, along with some applications of ion chromatography in industry. Ion chromatography systems are described, as well as ion pair and ion exclusion chromatography, column packings, detectors, and programming. (TW)

This review covers methods for identification, characterization, and determination of rubber and materials in rubber. Topics include: general information, nuclear magnetic resonance spectroscopy, infrared spectroscopy, thermal methods, gel permeation chromatography, size exclusion chromatography, analysis related to safety and health, and…

Reviews techniques for the characterization and analysis of synthetic polymers, copolymers, and blends.
