前文中讨论了利用Noether定理分析具有点群对称性体系中有关的点称(pointy)守恒选择规则,并对热化学反应过程中轨道对称守恒问题作较深入的分析。本文则将讨论在有光子参与的过程(光谱跃迁过程与光化学反应过程)中有关点称守恒的选择规则,这些过程与热化学反应的一个重要不同点在于粒子数不守恒。光子在有关过程中湮灭或产生,因此必须考虑光子的内禀点称。光子的内禀点称一般为其偏振方向矢量所相应的一维既约表象的特征标。此外,在本文中还将对各种过程(包括热化学反应在内)进行算符化处理,得到各种过程算符,对于点称守恒允许或禁阻的情况,相应算符将有明确的反映。
In the previous article, we discuss the use of Noether’s theorem to analyze the pointy conservation rules of point-symmetric systems and analyze the conservation of orbital symmetry in the thermo-chemical reaction. This article will discuss the selection rules for the conservation of related points in photon-participating processes (spectral transitions and photochemical reactions). One important difference between these processes and thermo-chemical reactions is the non-conservation of particles. Photons are annihilated or generated in the relevant process, so the intrinsic point of photon must be considered. The intrinsic point of photons is generally called the one-dimensional feature of the approximate representation of the direction of its polarization vector. In addition, various processes (including thermo-chemical reactions) will be operatorized in this paper to obtain various process operators. For the sake of permitting or forbidding the calling, the corresponding operator will have a definite reflect.
