The SiC2 radical was found to be formed easily by the 193 nm photolysis of phenylsilane, both in cell and molecular beam conditions. The reactivity of the radical in the ground state was quite low. Even in the electronically excited à state, it is inert towards saturated hydrocarbons. The rate of quenching by an unsaturated hydrocarbon, C2H4, is found to be 9.6 × 10−11 cm3 molecule−1 s−1.
发现在细胞和分子束条件下,苯硅烷的193 nm光解均易于形成SiC 2自由基。基态的自由基的反应性很低。即使在电子激发状态下,它对饱和烃也是惰性的。发现由不饱和烃C 2 H 4淬灭的速率为9.6×10 -11 cm 3分子-1 s -1。
