Abstract

Results of a spectral survey of IRC+10216 using the James Clerk Maxwell Telescope are presented. A total of 46 spectral lines were detected from 11 different identified molecules and isotopomers, and an additional eight weak features are unidentified. The excitation temperatures between different Ka ladders of SiCC range from 145 to 227 K, suggesting that excitation by IR radiation is important for this molecule. The total column density of SiCC is found to be 2.8 x 10 exp 15/sq cm.
