摘要: Abstract In this Letter, we present mechanism and direct dynamics calculations for the reaction of EtSiH 3 with atomic O ( P) first time. This takes place through three possible channels: H abstraction from silyl group (SiH ), methylene (CH 2 methyl ). On basis ab initio data, properties each channel have been deduced by canonical variational transition state theory (CVT) small-curvature tunneling (SCT) contribution over a wide temperatures range 200–3000 K. The results show that effect is small in lower temperature range, curvature important all channels.
