The mm-wave spectrum of the C-star envelope IRC+10216 has been continuously surveyed between 129.0 and 172.5 GHz with the IRAM 30-m telescope. 380 lines are detected, of which 317 have been identied. The iden- tied lines arise from 30 dierent molecules and radicals which, in their vast majority, are not observed in hot and dense interstellar clouds such as Orion A or W3(OH). Actually, half of the molecular species identied in the mm-wave spectrum of IRC+10216 were rst observed in the course of… Expand

The Abundance of C2H4 in the Circumstellar Envelope of IRC+10216.
TLDR
High spectral resolution mid-IR observations of ethylene (C2H4) towards the AGB star IRC+10216 were obtained using the Texas Echelon Cross Echelle Spectrograph (TEXES) at the NASA Infrared Telescope Facility (IRTF), and it is found to be rotationally under local thermodynamical equilibrium (LTE) and vibrationally out of LTE.
