Mid-infrared lines of ethylene (C2H4) were detected in the 1980's in the circumstellar shell of the dust obscured AGB star IRC+10216 using a novel heterodyne technique. Due to the symmetry of the molecule ethylene does not have a permanent dipole moment and there are no strong microwave rotational transitions. Ethylene is best detected through the ν7 out-of-plane bending mode at 10.5 μm. To confirm the previous ethylene detections and to settle outstanding questions about the ethylene excitation temperature and radial abundance we re-observed the 10.5 μm ν7 band. Observations were made with the cryogenic grating spectrograph TEXES and the IRTF. The observed spectra of the 10.4 - 10.8 μm region reveal a selection of ethylene, ammonia, and silane lines. We report on an analysis of the ethylene spectrum.
