Facilities Overview

The Todd Wehr Chemistry Building is centered in the Wehr Science Complex on the Marquette campus. The six-story chemistry building, which has recently undergone extensive renovation, provides 100,000 square feet of research and teaching space equipped with the modern instrumentation required for chemical research.

Facilities for Research: Major Research Instrumentation

NMR Facilities

The on-site NMR facility is managed by Dr. Sheng Cai and includes 300 MHz (with autosampler), 400 MHz and 600 MHz NMR instruments. These instruments provide us with important structural data to help determine isomeric structures.

X-Ray Diffraction Facilities

The department also has small-molecule single-crystal and powder XRD instruments that provide diffraction data, which is used to calculate precise 3D structures of catalysts and small molecules obtained as single crystals. The facility is managed by Dr. Sergey Lindeman, the staff crystallographer, and is also supported in part by Dr. Raj Rathore.

Agilent GC-MS

Maintained by Dr. Ruchi Shukla and Mark Bartelt.


The MALDI is very useful for determining the mass of high molecular weight compounds, such as proteins. It is maintained by Dr. Sheng Cai.

Thermo/Nicolet IR Spectrometer

With a probe capable of running solid samples.

Nicolet IR Spectrometer

Photon Technology Fluorimeter

Supported and funded in part by Prof. Evgueni Kovriguine.

Perkin-Elmer polarimeter

For the characterization of chiral compounds.

Virtis Lyophilizer (freeze dryer)

Facilities for Teaching

The Todd Wehr Chemistry Building has newly renovated labs and outstanding teaching facilities. General Chemistry labs contain MeasureNet workstations that are outfitted with a variety of chemical probes for data acquisition, and each lab has smart podiums and projection systems. Organic labs feature individual hoods for each student. All of our research instrumentation is available for use by undergraduates in the classroom and in research.

Other Facilities

Access to the Raynor Memorial Libraries resource catalog is available from numerous computers in the chemistry building. Free, unlimited computer time is available to students and faculty across campus at the Raynor Memorial Libraries and there are many state-of-the-art PCs throughout the Chemistry Department. Our faculty, staff and students also have access to the high-speed University Computer Cluster (Pere).
