A new computer-based molecular visualization tool has been developed for teaching, and learning, molecular structure. This java-based jmol Amalgamated Molecular Visualization Learning Environment (jAMVLE) is platform-independent, integrated, and interactive. It has an overall graphical user interface that is intuitive and easy to use. The…

A laboratory experiment is presented for the upper-level undergraduate physical chemistry curriculum in which the ternary phase diagram of water, 1-propanol and n-heptane is measured using proton nuclear magnetic resonance (NMR) spectroscopy. The experiment builds upon basic concepts of NMR spectral analysis, typically taught in the undergraduate…

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…

We studied the effect of formative assessment and feedback on learning. Students produced phylogenetic trees based upon morphological and molecular data. The trees were projected in class, feedback provided, and the process repeated twice with new data. Assessment revealed that these in-class modules resulted in significant improvement in student…

Presents the spectra of the flames of three gaseous mixtures, together with analyses of the rotational, vibrational, and electronic contributions to the spectra. (MLH)

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 exercises using simple ball and stick models which students with no chemistry background can solve in the context of the original discovery. Examples include the tartaric acid and benzene problems. (GS)

Chemical bonding, for most simple complexes, is described in the Mulliken-Walsh Molecular Orbital (MO) theory. (CP)

The purpose of this paper is to show how symmetry selection rules can be used to determine whether certain of the electronic transitions exhibited by the title compounds are allowed or forbidden by symmetry. (Author/CP)

Reviews the phase transfer technique for conducting reactions between molecules with widely different solubility properties. (SL)

Discusses the perturbational molecular orbital (PMO) approach for qualitative prediction of reactivities and stabilities of organic molecules. (SL)

Describes a 12 hour minicourse in Huckel molecular orbital (HMO) theory presented as part of a senior level chemical bonding course. (SL)
