Interactive OChem Structures and Animations
by Carl LeBlond - Thursday, October 16, 2014, 8:20 PM

I have developed quite a few interactive demonstrations and animations for my online courses over the past two years.  Unfortunately most of it is buried in glossaries or various deep in course pages on EasyOChem and I forget about them.  In an effort to make them more accessible I took an hour and compiled links to all of them.  Most of them are 3D JMOL or JSMOL structures and animations.  There's also a few animated GIF's I did with GIMP.  These are all in the EasyOChem Glossary and Organic Chemistry I course.
