Render 2-D and 3-D molecular structures and spectra from open chemical data files and create or modify chemical structures via a chemical editor. 

Molecular display and chemical editing features can be utilized across course sections and course activities, including assignment prompts, forum posts, and quiz question and answers. An Atto editor plugin enables users to sketch and edit molecules, or upload existing chemical molecule and spectrum files. 

Molecules rendered with the JSmol library allow for user interaction (zoom, rotate, pan, etc.) and can be customized with custom commands.

Specific display options are available for .mol, .jdx, and .pdb file types.
