Many mode-specific behaviors in the gas phase and at the gas-surface interface have been reported in the past decades. Infrared activation of a reagent vibrational mode is often used to study these reactions. In this work, an inexpensive and easily applied scheme using microwave irradiation is proposed for activating complex-forming reactions by transferring populations between closely spaced resonances. The important combustion reaction of H + O₂ ↔ O + OH is used as a model system to demonstrate the feasibility of the proposed approach. The existence of a nonzero transition dipole moment matrix element between two highly excited resonance states separated by a small energy gap in the model system may allow one to use microwave irradiation to intervene and control the model reaction. The high energy resonance states of the model reaction can also release their energy by photon emission, which is in agreement with the experimentally observed chemiluminescence process.

微波辐射活化复杂区域中的反应

在过去的几十年中，已经报道了在气相中和在气体-表面界面处的许多特定于模式的行为。试剂振动模式的红外激活通常用于研究这些反应。在这项工作中，提出了一种廉价且易于应用的使用微波辐射的方案，该方案通过在紧密隔开的共振之间转移种群来激活络合物形成反应。H + O ₂的重要燃烧反应↔O + OH作为模型系统来证明所提出方法的可行性。在模型系统中由小能隙隔开的两个高度激发的共振状态之间存在非零跃迁偶极矩矩阵元素，这可能允许人们使用微波辐射进行干预并控制模型反应。模型反应的高能共振态也可以通过光子发射释放能量，这与实验观察到的化学发光过程一致。
