Department of Chemistry

Major Departmental Instrumentation

  • NMR: 300 MHz (Varian Gemini) and 400, 500 and 700 MHz (Bruker) spectrometers.
  • X-ray Diffraction: Bruker SMART APEX CCD X-ray Diffractometer System equipped with a Kryo-Flex low temperature attachment; Bruker X-ray powder diffractometer. The Department has a full-time staff specialist in X-ray crystallography.
  • Raman instrumentation: Tunable (193-205 nm, 257-280 nm, 386-420 nm, and 772-840 nm) Indigo S laser system from Positive Light, a liquid nitrogen-cooled CCD camera from Roper Scientific, a home-built double spectrograph with a high throughput in the deep UV region, a confocal Raman microscope and an atomic force microscope (AFM).
  • Electron Spin Resonance Spectrometers
  • Circular Dichroism: J-815 Circular Dichroism (CD) Spectropolarimeter (Jasco, Inc) with Peltier and circulator temperature control systems for circular dichroism spectral and kinetic measurements at different temperatures.
  • UV/IR:
    • Lambda-35 absorption spectrophotometer (Perkin Elmer) for routine UV/Visible absorption measurements. It is equipped with thermostating system for doing temperature measurements and with integrating sphere specifically designed to measure transmittance and reflectance of liquid, solid and powder samples at a broad angle;
    • Lambda-950 absorption spectrophotometer with enhanced capabilities (Perkin Elmer) for absorption measurements in high dynamic range and wide UV - Near IR spectral range;
    • Spectrum-100 FT-IR spectrometer (Perkin Elmer) with exchangeable sample accessories including sample shuttle, diffuse reflection and universal attenuated total reflection accessories;
    • Fluorolog-3 spectrofluorometer (Horiba Jobin-Yvon, Inc.) with time-correlated single photon counting (TCSPC) option for steady-state and kinetic fluorescence measurements. TSCPC allows doing time-domain lifetime fluorescence measurements with nanosecond time resolution. Accessories include solid sample holder, Dewar flask, and integrating sphere.
  • SFM-400 stopped-flow machine (Molecular Kinetics, Inc.) for measuring absorption and fluorescence kinetics in liquid samples.
  • DLS: DynaPro dynamic light scattering instrument (Wyatt Technology Corp.) for measuring hydrodynamic radius of particles in solution.
  • GC/MS: Several newer Varian Saturn 2100T GC/MS systems are available in individual faculty laboratories.
  • HPLC: Several analytical and preparative HPLC facilities equipped with diode-array detectors are available in individual faculty laboratories.
  • Glove boxes and controlled atmosphere chambers are available in individual faculty laboratories.

The Cell

The CELL is located in room CH 215 and is open daily from 9:00 am to 5:00 pm.
The Chemistry Electronic Learning Library (CELL) was created in 1995 under the directorship of Professor Bernard Laurenzi and has since been maintained with the financial support of alumnus Dr. Alan T. LeFor.

Situated on the second floor of the Chemistry building, the CELL is aesthetically pleasing and offers maximum comfort. It houses 22 PCs and offers nearly two hundred programs for plotting data, sending e-mail, accessing the internet, tutoring, organic and physical chemistry, 2D and 3D molecular modeling, word processing, and presentations. This software is also accessible 24/7 any place connected to the university ethernet.

Many of the lower division courses have integrated the CELL and its software into their curricula. When using the CELL as a classroom, faculty can broadcast any material appearing on a console PC to all of the other PC's within the room, including multimedia presentations.
