六十年代中期发展了讨论化学反应性的两类理论模型:一个是支配协同反应的轨道对称守恒原理;另一个是强调反应分子某些特殊轨道起主要作用的普遍化的微扰理论(Generalized Perturbation Theory)。前者很快被引入我国各类结构化学教材;后者则至今未被引起足够重视。其实这一理论在讨论化学反应性上的价值并不低于前者。在此简要介绍这个理论及其
Two types of theoretical models for discussing chemical reactivity were developed in the mid-1960s: one is the orbital symmetry conservation principle that governs the synergistic reaction; the other is the generalized perturbation theory that emphasizes the principal role played by some particular orbit of the reaction molecule (Generalized Perturbation Theory. The former was soon introduced into all kinds of structural chemistry textbooks in our country; the latter has not been given enough attention so far. In fact, this theory is not less than the former in discussing the value of chemical reactivity. Here is a brief introduction of this theory and its
