The first centimeter-wave transition of the recently identified SiC/sub 2/ radical has been observed in the envelope of the evolved carbon star IR +10216. The excellent agreement between our measured astronomical rest frequency and the predicted frequency, and our measured line intensity support the SiC/sub 2/ identification. The high-resolution line profile and mapping data are used to estimate the size of the IRC +10216 SiC, envelope and the abundance of SiC/sub 2/ relative to H/sub 2/.
