Description: 

A series of JAVA applets of Tanbe-Sugano diagrams were developed by Prof. Robert Lancashire at the University of the West Indies.  These diagrams allow students to determine deltao/B values based on ratios of peak energies without the pain of rulers and drawing lines.  There are also features that allow a person to input values and automatically calculate certain parameters.  You can also quickly find values of delta_o and B for certain complexes via a drop-down menu on some of the pages (e.g. Cr3+ complexes).    

Learning Goals: 

Students will be able to interpret absorption spectra using the provided Tanabe-Sugano diagram applets.

Implementation Notes: 

I use these applets when teaching Tanabe-Sugano diagrams in my class and students get significant practice with the applets through homework assignments and a lab experiment.

Note that you cannot use Chrome (Firefox or Internet Explorer both work) and you will likely need to add the website to your "safe" list in your JAVA settings in order for the applets to work.

Amanda,

Have you accessed this site recently?  I am accustom to creating security acceptions to make Java applets run but I am unable to make this site run (and I am using Firefox).

I just tried it now and could get it to work - but it is a pain.  I used firefox.  I added the website to my "exception" list.  (Start Menu -> JAVA -> Configure JAVA -> Security).  You then have to close and restart firefox in order for it to work.  

If you put this in as the "exception" site (http://wwwchem.uwimona.edu.jm/courses/Tanabe-Sugano/) then from the applets page all the versions should work (http://wwwchem.uwimona.edu.jm/courses/Tanabe-Sugano/TSapplets.html)

An update to the site includes several TS diagrams that don't require the JAVA security headache to access.  Hopefully the rest will come online at some point!

I have been trying to access this site with no luck. I have added the site to my exceptions list and I cannot get it to run. I have tried it on a Mac (Safari and Friefox) and on a Windows 10 machine (Microsoft Edge). Any thoughts?
