The Milsmann Group

Facilities and Techniques

Gloveboxes

 

Two MBraun inert atmosphere gloveboxes are the centerpiece of the lab and serve as workstations for the synthesis of air- and moisture sensitive compounds.

 

Each box contains two freezers for sample storage and low-temperature recrystallizations. Liquid nitrogen cold-wells allow work at very low temperatures.

 

Both gloveboxes are equipped with electrical and fiber optic feedthroughs to interface directly with instrumentation for electrochemical measurements as well as UV/vis absorption and fluorescence experiments under inert atmosphere.

Schlenk Lines

 

Fumehoods in the lab are equipped with custom-made Schlenk line manifolds build by our in-house glassblower. Manipulations of sensitive materials under vacuum or Argon atmosphere are routinely carried out by graduate and undergraduate researchers.

Solvent Purification System

 

Oxygen-free, dry solvents for the synthesis of reactive complexes are supplied by two Glass Contour solvent purification systems with a total of twelve organic solvents. These facilities are shared with the research groups of Prof. Jessica Hoover and Prof. Brian Popp.

NMR Spectroscopy

 

The Chemistry Department houses two NMR spectrometers (600 MHz and 400 MHz), which are available 24/7 for students and staff. The Milsmann Group uses both instruments for routine characterization of diamagnetic and paramagnetic compounds by 1H NMR spectroscopy. Additionally, one dimensional 13C and heteronuclear spectra and 2D correlation experiments are conducted if necessary for diamagnetic materials. For  advanced experiments, students are trained and assisted by Dr. Novruz Akhmedov.

X-Ray Crystallography

 

The Milsmann Group is one of the main users of the department's Bruker D8 Venture X-ray diffractometer. The determination of three-dimensional molecular structures by single-crystal X-ray diffraction is an important component of the full characterization of new transition metal complexes synthesized by students in the group. Data collection and analysis is performed by researchers in the group with expert support and training by Prof. Jeffrey Petersen.

EPR Spectroscopy

 

Paramagnetic compounds synthesized in the Milsmann Group can often be studied by EPR spectroscopy. The group maintains and supervises the department's Bruker EMX EPR spectrometer. X-band EPR spectra can be obtained from room temperature to 80 K and equipment for in-situ electrochemical and photochemical experiments is available.

Computational Chemistry

 

DFT calculations using the ORCA software package are conducted by the Milsmann Group to supplement the experimental results. Access to high performance computing systems is available via WVU's Research Computing Facilities.

Other Techniques

 

A number of further facilities are available in the WVU Chemistry Department. Infrared spectroscopy and room temperature magnetic susceptibility measurements are important tools for the characterization of new molecules synthesized in the Milsmann Group. Mass spectroscopy (including high resolution MS) is routinely applied for the characterization of air-stable chemicals.
