How to create diagrams

edit

Diagrams are invaluable for conveying precise chemical information without encroaching on the word count. For two-dimensional diagrams such as skeletal formulae or flow charts, a molecule editor is your best bet.

For images of three-dimensional molecules, use molecular graphics software, such as Accelrys DS Visualizer, a free downloadable application for Windows. A tutorial on how to use DS Visualizer is available here.
