分子结构的建立Z-matrixGaussViewSpartan-中正大学 第四章. 分子結構的建立(Z-matrix, GaussView, Spartan)在從事化學計算中,通常在最初的步驟中需要輸入分子結構(Z-matrix)。一般可將分子結構的輸入方式分成三種,分別是使用:(1) 直角座標(cartesian coordinates)(2) 分子內部座標(internal coordinates or Z-matrix...

The Z-matrix formulation of Brown and Light [J. Chem. Phys. 101, 3723 (1994)], based on a Kohn variational principle for a general class of finite-range scattering functionals, is applied to electron-molecule collisions employing a mixed basis of Gaussians and finite-element interpolation poly...

The integrals are expressed in terms of the general overlap integrals. An explicitly correlated Cartesian ...
正态分布(Normal distribution),也称“常态分布”,又名高斯分布(Gaussian distribution)。若随机变量X服从一个数学期望为μ、方差为σ2的正态分布,记为N(μ,σ2)。其概率密度函数为正态分布的期望值μ决定了其位置,其标准差σ决定了分布的幅度。当μ = 0,σ = 1时的正态分布是标准正态分布。 Z分布,即标准...

There are restrictions on the size of a Z-matrix: the maximum number of variables and the maximum number of atoms within a calculation. These are set consistently for a maximum of 250,000 real atoms (including ghost but not dummy atoms), and a maximum of 250,000 Z-matrix centers (atoms...
