摘要：

Absolute rate constants have been measured for the reaction of SiH2 (1A1) with C2H4 at room temperature in highly diluted ps mixtures with Ar and SF6. Rate constants are pressure dependent consistent with a third-body mediated association process. This is supported by RRKM calculations on silirane (silacyclopropane). Differences with the reaction of CH2(1A1)+C2H4 are explained on energetic grounds.
