C3H8 and C3H4 in Titan's atmosphere

Abstract

Four bands of propane C3H8 and two of methyl acetylene C3H4 have been identified in the Voyager IR spectrum of Titan. Stratospheric abundances of 2 × 10−5 for C3H8 and 3 × 10−8 for C3H4 have been determined for the mid-latitude region. A feature at 1,154 cm−1, previously assigned solely to CH3D, is now identified at least in part due to C3H8.
