摘要：
振动强光-物质耦合为利用红外微腔控制化学反应活性提供了一种有前景的方法。尽管近期研究已考察了这一现象的潜在机制，但许多重要问题仍未解决，包括何种类型的反应可以被修饰以及这种修饰能够实现到何种程度。在本研究中，我们探索了弱和强光-物质相互作用区间下微腔中黑体红外辐射解离（BIRD）的动力学。利用主方程方法，我们模拟了红外场约束和振动强耦合对双原子分子BIRD速率的影响。我们提出了一个框架，解释红外微腔如何影响BIRD动力学，并强调了泛频跃迁在该过程中的重要性。我们的发现勾勒出了能够实现BIRD速率显著增强或轻度抑制的条件，为在红外谐振器内控制化学的实际局限性和新策略提供了见解。
英文摘要：
Vibrational strong light-matter coupling offers a promising approach for controlling chemical reactivity with infrared microcavities. While recent research has examined potential mechanisms for this phenomenon, many important questions remain, including what type of reactions can be modified and to what extent this modification can be achieved. In this study, we explore the dynamics of Blackbody Infrared Radiative Dissociation (BIRD) in microcavities under weak and strong light-matter interaction regimes. Using a Master equation approach, we simulate the effects of infrared field confinement and vibrational strong coupling on BIRD rates for diatomic molecules. We present a framework explaining how infrared microcavities influence BIRD kinetics, highlighting the importance of overtone transitions in the process. Our findings outline the conditions under which significant enhancement or mild suppression of BIRD rates can be achieved, offering insights into the practical limitations and new strategies for controlling chemistry within infrared resonators.
