The Symyx Chime plugin (formerly MDL Chime) enables your browser to display three-dimensional models of chemical structures. Chime can read various file types
and offers an optional link between chemical structure and spectra.
If Chime is installed properly on your system, three 3D molecules in different file types should appear on the left side.
Before you continue with the Shockwave-Player test page, the following short manual will show you some of the
most important features of Chime.
In addition, some 3D molecules can be controlled by scripts. Various actions can be activated by clicking Chime buttons, as shown
on the chlorophyll molecule on the upper left side.
The structures displayed here can be rotated in every direction by dragging with your mouse on the Chime screens.
You can zoom in and out by holding down your shift key while dragging your mouse up and down on the Chime screens.

You can move the 3D structures by holding down the Ctrl key and your right mouse button while moving your mouse across the Chime screen.
