本文用一个简单的脉冲诱导模型分析了NO分子在Pt（111）表面的价电子激发下在转动能级N（J）上的脱附分布。lnN（J）和（Er）1/2之间存在线性关系，其中Er是脱附分子的转动能。激发态的寿命和使用这种依赖性估计的激发态的临界停留时间被发现彼此接近（~10− 15 s）。的频率和振幅的倾斜振动的吸附分子在激发态的估计。
The distribution of NO molecules desorbed from a Pt(111) surface due to valence electron excitation over rotational energy levelsN(J) is analyzed using a simple impulse-induced model. A linear dependence is found between lnN(J) and (Er)1/2, whereEris the rotational energy of the desorbed molecules. The lifetime of the excited state and the critical time of residence in the excited state estimated using this dependence are found to be close to one another (~10−15s). The frequency and amplitude of the tilting vibrations of the adsorbed molecules in the excited state are estimated.
