Bond angle calculation
Experimental group used HyperChem to rotate molecules and measure bond angles
Control groupused the PocketPCs to view structures in color, but with no rotation capability

The recent proliferation* of fast, interconnectedunderutilized cpus

A computing Grid is analogous to an electrical power grid. The user simply “taps” into the resource (with permission), but is usually unaware of the origin of the resource.
Functions can be selected from lists at the top left, dragged onto the workspace and joined.
The entire workflow can be hidden
in a single multifunction box
Submitting a Gaussian job can be as simple as selecting the input file name (from a variety of file types) and the desired output file name.
Note C & N along the Y axis, the midpoint of their bond at the origin
