在自旋相关的自由基对反应理论中，自由基对的时间演化，包括化学动力学的影响，由刘维尔形式主义中的主方程描述。对于化学动力学的描述，在文献中已经制定了一些可能的反应算子。在这项工作中，我们提出了一个框架，允许一个统一的描述的各种建议的机制和形式的反应算子的自旋选择性重组过程。主方程可以从与外部自由度相互作用的自旋系统的微观描述中导出的概念的基础上，有可能深入了解潜在的微观过程，并开发一种系统的方法来确定具体情况下的反应算子的具体形式。
In theories of spin-dependent radical pair reactions, the time evolution of the radical pair, including the effect of the chemical kinetics, is described by a master equation in the Liouville formalism. For the description of the chemical kinetics, a number of possible reaction operators have been formulated in the literature. In this work, we present a framework that allows for a unified description of the various proposed mechanisms and the forms of reaction operators for the spin-selective recombination processes. On the basis of the concept that master equations can be derived from a microscopic description of the spin system interacting with external degrees of freedom, it is possible to gain insight into the underlying microscopic processes and develop a systematic approach toward determining the specific form of the reaction operator in concrete scenarios.
