The absolute infrared intensities of transitions in the _9 band of ethane have long been a subject of controversy (Gunson 1996, Daunt 1984, Henry 1983, Auwera 2007, and references therein). Improving the ethane 12 µm database is one of the goals of this work. The spectra here acquired was obtained using the NASA Heterodyne Instrument for Planetary Wind And Composition (HIPWAC) in a laboratory setting. HIPWAC, in this environment, makes use of a blackbody source and a gas absorption cell. Observations were carried out from P(10) at 858.1583905 cm_1 to P(32) at 839.1958112 cm_1 of the 646 laser. The observational range is ± 3GHz centered on each laser line. HIPWAC has the ability to measure spectra by using infrared heterodyne techniques, in which an infrared source is combined with a laser local oscillator and focused on a photomixer, where the difference frequency between the source and laser is retrieved and analyzed. Using these techniques HIPWAC is able to achieve a very high resolution (_/__ > 106 ) and a high frequency specificity (> 10_8 ) in order to study low-pressure gases. The spectra was retrieved using an Acoustic-Optical Spectrometer (AOS) with a sampling interval of 1 MHz. The detector was a liquid Helium cooled HgCdTe Photomixer. The ethane was research grade (99.96 %) obtained from Matheson Gas Products. The gas was contained in a 30 cm straight-path cell with ZnSe windows. The gas pressure was 0.709 Torr, as measured by an MKS Baratron gauge, at a temperature of 26 degrees Celcius. Additional measurements were also done at 1.4 Torr and 2.8 Torr. The spectra acquired is double sided and was fitted using an IDL program. The quantum assignments were taken from previous atlases (Tennessee/GSFC and GEISA). Currently, similar measurements are also being done on Allene and OCS. In the future we would like to incorporate Quantum Cascade Lasers in our system to replace our CO2 gas lasers. Quantum Cascade lasers are very small solid-state devices with an output power of about 100 mW and limited tunability.
