This 1999 presentation gives an overall introduction to the ChemAxon's Marvin family that was launched in those years. Marvin is an applet package for drawing and visualizing chemical structures and substructures and it can be used by anyone with a web browser. The presentation mentions among the major advantages of the Marvin that it is faster than the similar applets because it is modularized, it can handle many file formats and it is highly configurable and controllable. After the general introduction to the Marvin two products of the family is described thoroughly. The first is the MarvinSketch which is a tool for drawing chemical structures. The other is MarvinView that is a 2D/3D viewer that can display a molecule, or many molecules in a table. The 3rd International Electronic Conference on Synthetic Organic Chemistry (ECSOC-3) Download
