Molecular representation l Chime (MDL Information Systems)  Chime plug-in, from  Example: l The plug-in displays 2&3D molecules directly within a web page and works with most Browsers (but not Internet Explorer!) on Windows and Macintosh. The molecules in the web page are "live," meaning they are not just pictures, but chemical structures that can be rotated, reformatted, and saved in various file formats. l Anyone with a knowledge of HTML can add structures to their research projects, tutorials, newsletters, journals, and presentations published across an intranet or the Internet.

Chemsymphony//JMol Lite version from  Example: /chem/chemsym.htm /chem/chemsym.htm l Java applet (Best example: Jmol) l An applet is a program written in the Java programming language that can be included in an HTML page, much in the same way an image is included. When you use a Java technology-enabled browser to view a page that contains an applet, the applet's code is transferred to your system and executed by the browser. See our ‘official webpage’ l

VRML l Virtual Reality Modeling Language is a platform- independent file format for sharing 3D worlds on the Web. VRML worlds can be interactive and animated, and can include embedded hyperlinks to other Web documents.  Example: “Molecule of the month”  or  ws05.pc.chemie.th-darmstadt.de/vrml/ 
