Organic Chemistry at Penn State: Marvin Applets

MARVIN APPLETS

The Marvin applets are developed by ChemAxon. We use them here with their kind permission.

To view Instructions on how to use the applet select "Help" or the question mark ("?"). To view help files, pop-up blockers have to be disabled. Alternatively, you may click here.
To activate a free floating and resizable applet select: View -> Sketcher Window
To save the drawing as a graphic file to be used as an attachment in our Organic Discussions select: File -> Save image -> JPEG
To view the drawn molecules in 3D select: View -> Open 3D Viewer
To view various conformation of a drawn compound, in 3D Viewer select: Edit -> Add -> Explicit H atoms, then view conformations by selecting: Edit -> Clean -> 3D -> Select conformer.

Notes:

You may download a fully functional free-standing MarvinSketch with calculational tools directly from ChemAxon. This version of the applet remains open even if the browser window is closed. It can perform many interesting calculations, including drawing of resonance forms. The download works fine with Internet explorer, but other browsers may require some setup.
There is no guarantee that all conformational minima are going to be found by the applet, and in some cases the lowest energy conformation might be selected incorrectly by a simplified algorithm used by the program.
For conventions on drawing and viewing chiral structures read the stereochemical tutorial. MarvinSketch is able to assign absolute stereochemistry to stereogenic centers. Chiral shapes are not recognized. Fischer projections cannot be used to designate stereochemistry.
