The Todd Wehr Chemistry Building is centered in the Wehr Science Complex on the 向日葵视频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.

NMR Facilities

The NMR Facility provides access to high field solution NMR instrumentation. It includes 300 MHz, 400 MHz and 600 MHz (with cryoprobe) instruments. These instruments provide us fast spectra acquisition in daily routine 鈥媋s well as 鈥媘ultidimensional experiments. The facility is managed by Dr. , the staff spectroscopist.

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. Alexander Erickson, the staff crystallographer.

Shimadzu GC-MS

Gas chromatograph-mass spectrometer, used for identifying molecules in complex mixtures.

Agilent GC-MS

Maintained by Dr. Ruchi Shukla.

Shimadzu HPLC

 

High-pressure liquid chromatograph, used for separating molecules in aqueous solutions.

Agilent 7100 Capillary Electrophoresis

Used for separating mixtures based on flow in an electric field.

Bruker MALDI MS

The MALDI is very useful for determining the mass of high molecular weight compounds, such as proteins.

Agilent Cary 5000 uv/vis/IR Spectrophotometer

Advanced spectrophotometer for accurate spectral measurement from the UV (175 nm) to the mid-IR (3300 nm). Maintained by Dr. Ruchi Shukla.

Thermo/Nicolet IR Spectrometer

With a probe capable of running solid samples.

Nicolet IR Spectrometer

Photon Technology Fluorimeter

Perkin-Elmer Polarimeter

For the characterization of chiral compounds.

Perkin Elmer Analyst 100 Atomic Absorption

Used for determining the presence and amounts of mostly metallic ions in solutions.

Virtis Lyophilizer (freeze dryer)

• The department also has transient absorbance systems for the study of processes over short (ns) and (coming soon) ultra-fast (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 ultra-sensitive 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.
