Indiana University Molecular Structure Center. The IUMSC web serveris designed as a resource for the professional crystallographers in the IUMSC and their collaborators.   It is also a resource to others who have an interest in the structure of molecules.  The Java applet, shown below, is one of several graphics tools that are available to examine the sometimes surprising and complex molecules one encounters in nature and in the laboratory.
