Bruker Avance II NMR Spectrometer
A nuclear magnetic resonance spectrometer is used to determine the structures of molecules. Our spectrometer is a three-channel instrument equipped with a variable-temperature unit and 5 mm TXI/Z-gradient three-channel indirect detection probe 5 mm BBO/Z-gradient two-channel broadband probes. This instrument is also capable of CP-MAS solids experiments and has a 120 slot autosampler. Spectra are analyzed using TopSpin, Sparky and iNMR.

Rigaku XtaLAB Mini II XRD Single crystal X-ray diffractometer
An X-ray diffractometer is used to determine the three-dimensional structures of molecules in the crystal state. The diffractometer is equipped with a Mo-K radiation source(l= 0.71073 Å) and cryogenic sample cooling. Reflections are indexed, integrated, and corrected for Lorentz, polarization, and absorption effects using CrysAlis Pro with SCALE3 ABSPACK scaling algorithm. Structures are solved by intrinsic phasing using Olex2. Hydrogen atom coordinates are assigned geometrically and constrained to ride on their parent atoms.

HPLC Liquid Chromatography Systems
HPLC liquid chromatography is used to separate molecules in a solution mixture. Both systems have autosamplers and Diode Array UV/Visible detectors for detecting and quantifying the molecules in the mixture. Chromatograms are collected and analyzed using Agilent's ChemStation software.

Cary UV/Visible Spectrophotometers
UV/Visible spectrophotometers are used to measure the absorption of visible and ultraviolet light by molecules dissolved in a solution. The department has 4 Cary-50 UV/Visible spectrophotometers, each having a Peltier temperature control unit. The department also has a high resolution UV/Visible spectrophotometer that contains Cary-14 optics, and which has been recently upgraded with OLIS electronics and software.

Thermo Nicolet iS5 with iD7 ATR (x2)
A Fourier-transform infrared spectrometer is used to analyze vibrational motions within a molecule, and can be used to identify molecules and groups of atoms within molecules. Sampling accessories for these instruments include attenuated total reflectance and diffuse reflectance. In addition to DTGS detectors, there is an MCT detector available for use with the Nexus benches.

Blugold Super Computing Cluster
Computational work in the Chemistry Department is carried out on the Blugold Supercomputer Cluster (BGSC), which is maintained by Learning and Technology Services at UW-Eau Claire. The cluster has seven 8-core nodes, four 12-core nodes and thirteen 20-core nodes for a total of 364 cores. Several of the nodes are gpu equipped. The cluster job scheduling software is Slurm.
Software resources on the cluster include Gaussian, Q-chem, Mathematica, the Intel ifort compiler, and the PGI Fortran compiler. There are four research active groups in the chemistry department making heavy use of the cluster.

Photophysics SX.18MV Stopped-Flow System
A stopped-flow instrument is used to quickly mix two solutions to initiate a reaction and to then monitor the kinetics of the reaction. Our two-syringe system has a minimal dead time of ~1.0 ms and can measure spectra from 275 to 700 nm using a PMT, diode array, fluorescence and circular dichroism detection for sample temperatures from 2.0-80.0 °C.
