"Web-Ed" Articles Only@JCE Online
Articles published here take advantage of the digital medium to include dynamic, interactive, colorful elements that cannot be published in the print medium.

The articles below are available exclusively at JCE Online.
Filling in the Hexagonal Close-Packed Unit Cell
Robert C. Rittenhouse, Linda M. Soper, and Jeffrey L. Rittenhouse

This electronic version of a paper by the same title published in this Journal (J. Chem. Educ. 2006, 83, 175) includes calculations, 3D computer models, and templates.

 
How a Photon Is Created or Absorbed

Giles Henderson, Robert C. Rittenhouse, John C. Wright, and Jon L. Holmes
HTML translation by Paul Wagner
This electronic version of a paper by the same title published in this Journal in 1979 (J. Chem. Educ. 1979, 56, 631-635) makes only minor revisions in the text, but uses interactive graphics and animations to illustrate the points being made.

Moving Particles and Wave Packet Propagation: A Computer Animated Supplement
Giles Henderson
Authors and educators have frequently been frustrated by the inability of equations and graphs to properly convey the temporal qualities of dynamic systems. Here previously published articles are supplemented with computer animated motions as described by both classical and quantum methods.

Abstract
* J. Chem. Educ. 2000, 77, 134.

Stark Effects on Rigid Rotor Wavefunctions
Brad Logsdon and Giles Henderson
A quantum mechanical description of how the Stark effect influences molecular orientation is supplemented here with computer graphics and animation.

Original Article
* J. Chem. Educ. 1995, 72, 1021-1024. (PDF file; requires Adobe Acrobat Reader)

Animated Vibrational Modes of Triatomic Molecules
Giles Henderson and Christine Liberatore
Accurately scaled, digital animations of the complex vibrational motions of non-linear molecules, calculated using a simple matrix algorithm to characterize molecular vibrations, are presented for both linear (carbon dioxide) and non-linear (sulfur dioxide) triatomic molecules.

Abstract
* J. Chem. Educ. 1998, 75, 779.

Why Does the Middle Band in the Absorption Spectrum of Ni(H2O)62+ Have Two Maxima?
Myriam Triest, Guillaume Bussière, Hugo Bélisle, and Christian Reber
A fully quantitative model is presented 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.

Abstract
* J. Chem. Educ. 2000, 77, 670.
