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.
Both the spin-allowed and low-lying spin-forbidden transition energies are
calculated and displayed.
More recently an alternative approach was to rewrite the
on tablets, smartphones, etc. The conversions were done using swingjs code
from Prof Bob Hanson and are in beta mode at present.
d8 are now available.
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
- use the appropriate Tanabe-Sugano diagram to locate where the
ratio of the second to first peak matches that found experimentally.
- Tabulate the values of ν1/B', ν2/B',
ν3/B' from the Y-intercepts and Δ/B' from the
