Drawing Chemical Structures
Requires a Wolfram Notebook System
Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
Draw your own chemical structures with this Demonstration.[more]
First, select a structure and then click the "add" button. To move an object, click its far edges and drag it. To rotate an image, click nearer to its center and spin it to the desired angle.
The "undo" button deletes the last component added.
To insert an element, click the buttons at the top and drag the symbol anywhere.[less]
