 ===== On the Detection of Tetratrienediylidenesilylene =====
-Six transitions of tetratrienediylidenesilylene, also known as silapentatetraenediylidene, with //J"// between 11 and 27 were detected in the circumstellar envelope of CW Leo (IRC +10216) with the 45 m radiotelescope of the Nobeyama Radio Observatory between 36 and 86 GHz:\\
