Computer graphics play an important role in the visualization and understanding of molecules.
The red regions represent charge depletion and the blue areas represent charge accumulation. In particular, note the charge accumulation regions that form between each hydrogen molecule and the oxygen molecule as they approach each other. Creon Levit, a member of the NAS Systems Division's computational molecular nanotechnology group, has created an online reference resource on the visualization of molecular structure . The web site contains computer-generated images that show the properties of molecules and associated data. The group's purpose is to research the benefits of molecular nanotechnology for the aerospace arena and to advance this technology.
