Determines the corresponding normal modes for two molecules.
The normal modes are downloaded from the output files from a Spartan or Gaussian calculation.    

• Atoms are numbered from 0.
• You can find the atom numbers by running the applet once and then clicking on the atoms in the structure display. The atom names and numbers will be listed in the staus bar at the bottom-left of the browser window.
• Modes are numbered from 0.
• Supported file types:
  • Unix Spartan "output" files
  • PC Spartan ".spartan" files
  • Gaussian output files
• If your PC Spartan ".spartan" file gives you an error message about being too long, remove the first four lines or so using a text editor.
• To view a mode from just a single molecule use Mode Explorer.
• This applet requires the CHIME plugin.

General Strategy At first you won't know what atom numbers or mode number to enter into the text boxes. Don't worry. This is a multi-purpose applet. As you decide which atoms to align and which modes are interesting you will be able to fill in more choices. Just run the applet with what you know, then return to the applet, enter your new choices, and run it again.
