Facilities and Instrumentation


The Chemistry Department is located in Seeley G. Mudd Hall of Science which has been its home since 1975. A 1997 renovation of the building added additional space for instrumentation and laboratories dedicated to student-faculty research. An extensive collection of monographs and journals that support teaching and research in chemistry is located in the Laurence McKinley Gould Library. In addition, the library maintains multiple on-line resources for research in the chemical sciences including SciFinder Scholar and electronic journal access. The following equipment and instrumentation is available for coursework and research. Instruments which are used primarily or exclusively within a specific research group are indicated.
