报道了金属表面吸附分子的振动激发和去激发速率。被吸附的分子的解吸与激发过程竞争，导致“振动冷”的解吸分子。利用简单的速率方程，结合已有的实验数据，估算了NO分子在铂(111)表面的振动激发和去激发速率随晶体温度的变化。讨论了该方法在其他系统中的应用。
The rates for vibrational excitation and deexcitation of adsorbed molecules on metal surfaces are reported. The desorption of the adsorbed molecules is shown to compete with the excitation process, resulting in ‘‘vibrationally cold’’ desorbing molecules. Simple rate equations, together with the available experimental data, are used to estimate the rates for vibrational excitation and deexcitation of NO molecules on Pt(111) surfaces as a function of the crystal temperature. The application of this approach to other systems is discussed.
