The department is equipped with 3 ThermoElectron IR200 Fourier Transform Infrared (FTIR) spectrophotometers as well as a research grade ThermoElectron Nexus FTIR. IR enables us to determine the functional groups present in molecules, allowing us to identify the components in a sample. The FTIR is frequently used in Organic Chemistry I and II (CHM 160/170) and Advanced Synthesis Laboratory (CHM 380). These instruments have also been a part of The Art Conservation of Paintings (CHM 330) and Independent Study (CHM 500/501) projects, with student results appearing in publications in Tetrahedron Letters (Papers I and II).
Some of the funding for acquiring the FTIR instruments came from the Spectroscopy Society of Pittsburgh with matching funds provided by W&J. As part of our FTIR instrumentation, we have attenuated total reflectance (ATR) and direct reflectance accessories.
