The following pages will lead you through a tutorial showing examples
of the importance of shape in Chemistry.
Each of these pages displays a chemical molecule using a set of Java applets available from the open-source Jmol project ("open-source" means the applets and code are freely available for use and for development). These applets allow you to manipulate the molecular drawing in real time. Below are some instructions on the use of these applets: In the frame on the right is a display of the famous Buckyball molecule. To rotate the molecule, move the cursor inside the java frame while holding down the left mouse button. To access a pop-up menu, do a single click with the right mouse button while the cursor is inside the java frame. (Try doing a "zoom" to enlarge the molecule view). To measure a bond distance, double-click on two atoms. To measure a bond angle, do double-click, single-click, double-click on three atoms. To measure a torsion angle, do double-click, single-click, single-click, double-click on four atoms. To remove the measurements do a "refresh" with your browser to re-load the applet.
