Facilities and Resources 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 Spectrometers


The NMR facility is managed by Dr. Sheng Cai. External users are welcome - please contact Dr. Cai if you are interested.

X-ray Diffraction facilities

The department has small molecule single crystal and powder XRD instruments. The facility is managed by Dr. Sergey Lindeman, our staff crystallographer. External users are welcome - please contact Dr. Lindeman if you are interested.

The department also has MALDI and (coming soon) LC-MS systems.

Laser Spectroscopy facilities

  • The department has transient absorbance systems for the study of processes over short (ns) and (coming soon) ultrafast (fs) timescales.
  • A state-of-the-art Raman Spectroscopy facility houses four complete Raman systems utilizing Kr ion, Ar ion, He:Cd, Nd:YAG and dye lasers with PMT, ICCD, and diode array detection.
  • The laser analytical facility includes krypton ion, argon ion, and F-center lasers used in ultrasensitive instrumentation for chemical analysis and chromatographic detection.
  • The Chemical Dynamics Laboratory is equipped for the study of gas-phase reactions with an excimer laser, frequency doubled dye laser, and tunable infrared diode lasers.

Other facilities

The department has a variety of assorted equipment for research use including:

  • Fourier transform infrared spectrometers
  • UV-Vis spectrometers
  • Fluorimeter
  • Polarimeter
  • GC-MS instruments
  • Other smaller equipment

Additional support facilities include staffed electronics and machine shops.

Facilities for Teaching

The Todd Wehr Chemistry building has newly renovated labs, with 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).
