Tanabe-Sugano diagrams via Java applets

A set of Tanabe-Sugano diagrams has been generated as SVG images as a way of being able to generate large printed versions.

A number of Java applets were developed to aid in spectral interpretation, they were originally compiled with the JDK vs 1.5 for Windows but unfortunately no longer work with recent versions of Browsers due to security restrictions etc. unless perhaps exceptions to the site were added to the Java control panel for each user.

The applets

Both the spin-allowed and low-lying spin-forbidden transition energies are calculated and displayed.

More recently an alternative approach was to rewrite the code into JavaScript/HTML5. This enables the display of the TS diagrams on tablets, smartphones, etc. The conversions were done using swingjs code from Prof Bob Hanson and are in beta mode at present.

The JavaScript/HTML5 TS displays for d2, d3, d7 and d8 are now available.

General Procedure

A spectroscopy exercise, based on the spectra of some simple Cr(III) complexes, has been developed that uses both JSpecView and Jmol (now merged as JSmol) and the TS d3 applet. This can be further developed for other Cr(III) examples where needed.

Otherwise, see the more general instructions for additional information.
