This Web site, maintained by the Molecular Arts Corporation, is an excellent research tool for chemistry students. It contains a searchable database of more than 210,000 three-dimensional molecular models. The main focus of the site is the model display, which can be viewed in three sizes. You will need a VRML or Chime plug-in to view the models. Links to these free downloads are supplied on-site.
Text links are well defined and easy to follow from the left-side menu.
An online search tool is available on every page for locating models quickly. The interactivity of this site makes it fascinating to the serious chemistry student or anyone who is interested in molecular structures. All models can be viewed in full 3-D, rotated, or panned. The database is searchable by Formula, CAS Number, NSC Number, or Common Name. Included are tips for searching using any of the methods.
