Pittsburg State University
Department of Chemistry
The Chemistry Department strives to keep itself well-equipped with modern instruments and computers. The philosophy of the department is that all instruments are available for hands-on use by chemistry students in their courses and research.
Two Fourier-Transform Nuclear Magnetic Resonance spectrometers are located in Room 108 Heckert-Wells. Both instruments are used in teaching and research by students and faculty at PSU. The Chemistry Department welcomes inquiries into the use of these instruments by faculty at colleges and universities in this region and beyond. Appropriate use of these instruments by students and faculty visiting from other institutions is encouraged.
60 MHz Proton NMR
The 60 MHz Proton NMR spectrometer consists of a Varian EM-360 permanent magnet and an upgrade of the electronics by Anasazi Instruments. This instrument provides a way to introduce students to modern FT-NMR spectrometry. The "NUTS" software permits advanced NMR data processing. The instrument provides excellent low-field proton spectra of organic compounds. Relaxation time measurements and two-dimensional COSY experiments can also be performed.
Bruker DPX-300 NMR
The Bruker DPX-300 NMR spectrometer is an advanced instrument purchased in 1998 for $250,000 with the help of a grant from the National Science Foundation. The 7.05 Tesla superconducting magnet gives proton (H-1) spectra at 300 MHz and Carbon-13 spectra at 75 MHz. Dozens of different one- and two-dimensional experiments are possible with this instrument. The broadband probe for liquid samples permits spectra to be taken of many nuclei besides C-13 and H-1.
An important feature of the instrument is that it can be used to study solids with its Cross- Polarization/Magic-Angle-Spinning (CP/MAS) probe. Carbon-13 spectra of solid samples such as polymer powders are routine. The CP/MAS probe can also be used for spectra of many other nuclei. Both solids and liquids experiments can be carried out over a wide temperature range.
