Cannon (GCMP)  David M. Whisnant
H2 and Cl2 cannon: this is a resource in the collection "General Chemistry Multimedia Problems". In this problem we observe the reaction of hydrogen and chlorine and explore some related reactions. The reaction involves a radical mechanism initiated by light. General Chemistry Multimedia Problems ask students questions about experiments they see presented using videos and images. The questions asked apply concepts from different parts of an introductory course, encouraging students to decompartmentalize the material.

Prophine and Protoporphyrin  William F. Coleman, Randall J. Wildman
The WebWare molecules this month are from the article "Photochemotherapy: Light-Dependent Therapies in Medicine" by Edward P. Zovinka and Danielle R. Suneri. The first is a simple porphine, illustrating the ubiquitous four-nitrogen macrocycle, while the second is the protoporphyrin found in heme systems.

Photoelectric Effect  William F. Coleman
This is a series of simulations of aspects of the photoelectric effect. There is an animation of the experiment with four choices of incident radiation - low and high intensity "red", to represent low energy light and low and high intensity "blue" to represent higher energy light. Electron production is animated and there is an ammeter to simulate current flow. Additional simulations show the effect of light frequency and intensity. There is a link to a spreadsheet that allows students to choose a sample from among five metals. The spreadsheet includes several questions to be answered after working through the materials.

Luminescent Molecular Thermometers  William F. Coleman
The Featured Molecules this month come from the paper "Luminescent Molecular Thermometers" by Uchiyama, Prasanna de Silva, and Iwai exploring the many ways that photophysical properties can be used as temperature probes. They introduce a variety of molecule types, many of them now in our molecule collection. Excited states play a central role in this paper and it provides an opportunity to introduce students to some excited state properties.
