The kinetics experiments on the ligand-C[subscript 60] exchange reactions on (dihapto-[60]fullerene) pentacarbonyl tungsten(0), ([eta][superscript 2]-C[subscript 60])W(CO)[subscript 5], form an educational activity for the inorganic chemistry laboratory that promotes graphical thinking as well as the understanding of kinetics, mechanisms, and the…

Describes an experiment in which the beam of X-rays is simulated through the use of a laser as a monochromatic light source and the crystal is replaced by photographically prepared masks. A strong diffraction pattern as large as 20 cm. can be obtained. (GS)

Describes an experiment, for the general chemistry laboratory, intended to introduce the student to infrared spectroscopy. After being introduced to the theory of molecular vibrations on an elementary level, each student receives a list of 5-7 nickel (II) ammines to be prepared, analyzed and characterized by infrared spectoscopy. (MLH)

Describes an experiment designed for second-level summer school chemistry students enrolled in Great Britain's Open University. (GS)

Describes a dry-lab experiment in which the student is provided with a set of fluorescence spectra of quinine for study and interpretation. (MLH)

An introductory undergraduate physical organic chemistry exercise that introduces the harmonic oscillator's use in vibrational spectroscopy is developed. The analysis and modeling exercise begins with the students calculating the stretching modes of common organic molecules with the help of the quantum mechanical harmonic oscillator (QMHO) model.

A single-semester elective combines Mendelian and molecular genetics in a problem-solving format. Students encounter a genetic disease scenario, construct a family pedigree, and try to confirm their medical diagnoses through laboratory experiences. Encouraged to generate ideas as they test their hypotheses, students realize the importance of data…

Describes an undergraduate chemistry experiment in which an atomic absorption spectrophotometer is used for recording flame emission spectra of the diatomic carbon molecule. (MLH)

Includes a discussion of the structure of some molecules and the design of an experiment to replace CHEM Study Experiment 7. (GS)

Describes an experiment which monitors the population of the lowest triplet state by directly observing phosphorescence intensity as a function of time. Reviews the theory concerning triplet state lifetimes, describes the experimental apparatus and procedure, and presents the method and examples of data analysis. (GS)
