We have used the James Clerk Maxwell Telescope to observe 11 lines of SiCC with excitation energies up to 330 K above the ground state in IRC 10216. An excitation analysis indicates Trot = 43 ± 5 K within a given Ka ladder and Texc = 160 ± 50 K between Ka ladders. The column density of SiCC is estimated to be 3 × 1015 cm−2, more than an order of magnitude higher than previous estimates. |
