摘要
H + SiD4→D + SiH3D反应的阈值远低于H与CD4的相应交换反应。D原子带走了H原子的大部分初始平动能。当h原子的速度分布是各向异性时，d原子的速度分布也是各向异性。反应H + SiH3D的交换截面约为反应SiD4的一半。所有这些证据都得出这样的结论:这种交换的机制是一种反转。
Exchange reactions of hydrogen atoms with SiD4: an inversion mechanism?
The reaction H + SiD4→ D + SiH3D is found to have a much lower threshold than the corresponding exchange reaction of H with CD4. The D atom carries away most of the initial translational energy of the H atom. When the H-atom velocity distribution is anisotropic, the D-atom velocity distribution is anisotropic in the same sense. The exchange cross-sections for the reaction H + SiH3D are about one half of those for SiD4. All this evidence leads to the conclusion that the mechanism of the exchange is an inversion.
