"Web-Ed" Articles

"Web-Ed Articles" was a collection of articles from the Journal of Chemical Education that were augmented with digital assets that aided in the understanding of selected aspects of the article. The augmented, digital versions of these six articles have moved to supporting information for the article at the Journal web site.

Filling in the Hexagonal Close-Packed Unit Cell by Robert C. Rittenhouse, Linda M. Soper, and Jeffrey L. Rittenhouse  includes calculations, 3D computer models, and templates. J. Chem. Educ. 2006, 83, 175.

How a Photon Is Created or Absorbed by Giles Henderson, Robert C. Rittenhouse, John C. Wright, and Jon L. Holmes; HTML translation by Paul Wagner includes interactive graphics and animations to illustrate the points being made. J. Chem. Educ. 1979, 56, 631-635.

Moving Particles and Wave Packet Propagation: A Computer Animated Supplement by Giles Henderson supplements six previously published articles supplemented with computer animated motions as described by both classical and quantum methods. J. Chem. Educ. 2000, 77, 134.

Stark Effects on Rigid Rotor Wavefunctions by Brad Logsdon and Giles Henderson provides a quantum mechanical description of how the Stark effect influences molecular orientation that is supplemented with computer graphics and animation. J. Chem. Educ. 1995, 72, 1021-1024.

Animated Vibrational Modes of Triatomic Molecules by Giles Henderson and Christine Liberatore is supplemented with accurately scaled, digital animations of the complex vibrational motions of non-linear molecules, calculated using a simple matrix algorithm to characterize molecular vibrations, for both linear (carbon dioxide) and non-linear (sulfur dioxide) triatomic molecules. J. Chem. Educ. 1998, 75, 779.

Why Does the Middle Band in the Absorption Spectrum of Ni(H2O)62+ Have Two Maxima? by Myriam Triest, Guillaume Bussière, Hugo Bélisle, and Christian Reber presents a fully quantitative model to calculate the band shape of the absorption spectrum of octahedral nickel(II) complexes and to characterize its two energetically-close excited states. The double maxima are a consequence of interacting electronic states with potential energy surfaces crossing in the Franck-Condon region of the absorption spectrum. J. Chem. Educ. 2000, 77, 670.
