The D/H ratio in Titan's acetylene from high spectral resolution IRTF/TEXES observations

B. Bézard, C. A. Nixon, S. Vinatier +5

We report observations of deuterated acetylene (C${}_2$HD) at 19.3 $\mu$m (519 cm${}^{-1}$) with the Texas Echelon Cross Echelle Spectrograph on the NASA Infrared Telescope Facility in J…
