Old Dominion University Fourier Transform Infrared Spectrometer Laboratory Laboratory The Old Dominion University Fourier Transform Spectrometer Laboratory, under the direction of Dr. Peter Bernath, focuses on molecular spectroscopy and atmospheric remote sensing applications. The laboratory is located on the Old Dominion University campus, housed in the Department of Chemistry and Biochemistry. The laboratory uses a Bruker FTS 120/125HR Fourier transform spectrometer to assess pure and gas-broadened samples of hydrocarbon compounds useful in comparing to atmospheric chemistry of Jupiter, Saturn, Saturn's moon Titan, and exoplanets. The spectrometer currently used is Bruker IFS 120HR hardware with Bruker IFS 125HR electronics. The maximum optical path difference of the Fourier transform spectrometer is 4.2 m. A 20 cm long cold cell (25 C to about -50 C) with KBr windows is used in the sample compartment. The cell was cooled with a recirculating chiller that used ethanol. For measurements in the 3 micron region, a CaF2 beamsplitter and liquid N2 cooled InSb detector were used.
