Step 3
Examples of Vibrational Mode Displays



In order for the examples linked below to work, you must first get
Chime version 2.6 plugin for PC-Windows (includes JCAMP-DX viewer capability)

See the limits of testing of these vibrational displays.

STAY WITH NETSCAPE v 4.5-4.7;
UPGRADE INTERNET EXPLORER (TO VERSION 6);

UPGRADE CHIME (TO VERSION 2.6, SP4) .
IT SEEMS ADVISABLE! REMEMBER TO UNINSTALL CHIME BEFORE UPGRADES. ALSO, IF YOU ARE WORKING ON SETTING UP YOUR OWN WWW PAGES, BE WARNED THAT THE MIME TYPES THAT SERVE UP THE *.jdx, *.dx, *.pdb FILE TYPES CAN BE FLAKEY!


Spectral Tutorials Used at UMass-Amherst

FTIR-spectra were obtained on a Midac spectrometer, converted to JCAMP-DX format, and used in most of these examples. Computations of vibrational modes were accomplished on a PC or SGI workstation, using Spartan or Gaussian.


Single Example -- Unlinked Chime windows

This is a simple example of a page that shows a spectrum and a molecule. Both may be manipulated separately, but there is no linkage of the windows that show the two.

Single Example -- Linked simultaneous display

This is an example of a page that shows a spectrum and a molecule. Both may be manipulated separately, and there is a point-and-click linkage between the spectrum and a set of files that show molecular vibrational animations. The animations are a concatenated set of molecular geometries that are run as a "slide-show", and have been extracted by VIBREAD from computations.

Additional Spectroscopy problems used at University of the West Indies, Mona, Jamaica.
