JCE WebWare Examples
JCE WebWare is in many ways different from more traditional features of the Journal. Accordingly, this feature includes several different applications that fall within the general guidelines for this column. These certainly do not begin to represent the range of types of applications suited to JCE WebWare. That is for the creativity of our readers to determine.

All of these applications fall into the snippets category. A full paper might include details on the use of the forms menu in Excel to produce the interactive spreadsheets.To see the examples, click on the button at right and view the first four examples.


Examples from the Editor

Make Your Own MO Diagrams
William F. Coleman

Complete the given MO diagram pertaining to a second-row homonuclear diatomic molecule. Choose the appropriate MO diagram from either of two, and fill it with electrons by dragging the supplied symbols in turn to the appropriate blanks in the diagram.

Methane Symmetry Elements
William F. Coleman

Examine the symmetry elements of methane (CH4) in 3-D. Any one of the complete set of point symmetry operations for methane can be chosen. Appropriate axes of rotation and/or reflection planes are shown along with the molecule; the whole can be rotated arbitrarily along any of the three cartesian axes at the viewer's discretion for clearer viewing.

Close-Packed Worksheet
William F. Coleman

Separate 2-D close-packed layers are superimposed upon each other to represent three-dimensional packing. Each layer can be moved to any position relative to the other layers. Thus, trigonal close-packed sequences or hexagonal close-packed sequences, or even non-close-packed sequences, can be constructed. Each layer remains completely visible through objects of the other layers.

Interactive Spreadsheet Demos
William F. Coleman

Interactive Excel spreadsheets display hard-to-understand concepts in statistics, quantum mechanics, physics, and more. Parameters are adjusted by clicking on easy-to-use buttons or by using numeric input boxes. Graphs, tables, and/or figures are then created reflecting the change in parameters.
