Discovery of Methyl Silane and Confirmation of Silyl Cyanide in IRC +10216
Astron. Astrophys. 606, LL5 (2017).
6 sets of silyl cyanide, SiH3CN, transitions with J' between 9 and 17 (between 89 and 170 GHz) were detected with the IRAM 30 m telescope in emission toward the late-type C-rich star CW Leonis. The K level structure is partly resolved. At least some degree of blending by emission lines of other molecules is present.
