Reaction dynamics of OH + SiH ₄ → H ₂ O + SiH ₃ : a quasi-classical trajectory study on the PES-2

Excitation function σ ( E _coll ) for OH + SiH ₄ → H ₂ O + SiH ₃ (DZPE), showing the monotonic rise to a plateau near 4.9 Å ² above E = 6 kcal mol ⁻¹ . Mechanism fractions at E = 1 and E = 10 kcal mol ⁻¹ , showing the sideways to stripping-dominated transition.
