Frost提出的量子化学浮动球高斯轨道模型(A Floating Spherical GaussianOrbitals Model,即 FSGO)是一种定域化轨道模型,它摸仿经典的Lewis电子结构图象,每一对电子都用一个球型高斯轨道来描述,这些电子对分为内层电子,孤对电子和成键电子.由电子所占据的球型高斯轨道直接组成闭壳层体系的电子波函数,以能量最低原理对球型轨道的位置和半径进行优选.由于 FSGO 模型不是从分子轨道理论出发,得到的电子 Frost proposed a quantum chemical floating ball Gaussian orbit model (A Floating Spherical Gaussian Orbitals Model, or FSGO) is a localized orbit model that emulates the classical Lewis electron structure image, each pair of electrons using a spherical Gaussian Orbitals, these electron pairs are divided into inner electrons, lone pairs of electrons and bonding electrons.The spherical Gaussian orbit occupied by electrons directly forms the electron wave function of the closed shell system, and uses the lowest energy principle for the orbital Location and radius.As the FSGO model is not based on molecular orbital theory, the resulting electronic
