1 Atomic shell

+
+

+Set of contracted Gaussians differing only by the powers of \(x\), \(y\) and \(z\), with a +constant Angular_momentum.t, all centered on the same point. +

+ +

+In other words, it is the set of all contracted shells sharing the same center. +

+ +\begin{align*} +\chi_{n_x,n_y,n_z}(r) & = f(n_x,n_y,n_z) \sum_{j=1}^{n} \sum_{i=1}^{m} \mathcal{N}_{ij}\, d_{ij}\, g_{ij\,n_x,n_y,n_z}(r) \\ + & = (x-X_A)^{n_x} (y-Y_A)^{n_y} (z-Z_A)^{n_z} f(n_x,n_y,n_z) \sum_{j=1}^{n} \sum_{i=1}^{m} \mathcal{N}_{ij}\, d_{ij}\, \exp \left( -\alpha_{ij} |r-R_A|^2 \right) +\end{align*} + +

+where: +

+ +
    +
  • \(g_{ij\,n_x,n_y,n_z}(r)\) is the $i$-th PrimitiveShell.t of the $j$-th Contracted_shell.t
    • +
  • \(n_x + n_y + n_z = l\), the total angular momentum
    • +
  • \(\alpha_{ij}\) are the exponents (tabulated) of the $j$-th Contracted_shell.t
    • +
  • \(d_{ij}\) are the contraction coefficients of the $j$-th Contracted_shell.t
    • +
  • \(\mathcal{N}_{ij}\) is the normalization coefficient of the $i$-th primitive shell +(PrimitiveShell.norm_coef) of the $j$-th Contracted_shell.t
    • +
  • \(f(n_x,n_y,n_z)\) is a scaling factor adjusting the normalization coefficient for the +particular powers of \(x,y,z\) (PrimitiveShell.norm_coef_scale)
