Chem220 and Chem220js
Since its inception, Chem 220 [http://classes.yale.edu/chem220] has been hosted by the CLASSES server at Yale. This server has been decommissioned. Consequently, the site has been moved to http://ursula.chem.yale.edu/~chem220. You will automatically be transferred to the new URL if you use the older URL for about one year (2015). Chem 220 has been using Java Applets in four applications: a) Jmol molecules, b) electrostatic potential maps, c) molecular orbitals and d) NMR spectroscopy. You will need to set your Java Security at least on "high" and under Exceptions, add http://www.chem.yale.edu. When you come to a Java app, choose RUN.
There is more good news! The Java apps have been converted to JavaScript. In addition, the formats of some of these apps have been improved. Chem220js [http://ursula.chem.yale.edu/~chem220/chem220js] is now available. Moreover, you can access Chem220js on your mobile device!
