* Introduction
|
|
|
|
The atomic basis set is defined as a list of shells. Each shell $s$ is
|
|
centered on a nucleus $A$, possesses a given angular momentum $l$ and a
|
|
radial function $R_s$. The radial function is a linear combination of
|
|
/primitive/ functions that can be of type Slater ($p=1$) or
|
|
Gaussian ($p=2$):
|
|
|
|
\[
|
|
R_s(\mathbf{r}) = \mathcal{N}_s |\mathbf{r}-\mathbf{R}_A|^{n_s}
|
|
\sum_{k=1}^{N_{\text{prim}}} a_{ks}\, f_{ks}
|
|
\exp \left( - \gamma_{ks} | \mathbf{r}-\mathbf{R}_A | ^p \right).
|
|
\]
|
|
|
|
In the case of Gaussian functions, $n_s$ is always zero. The
|
|
normalization factor $\mathcal{N}_s$ ensures that all the functions of
|
|
the shell are normalized (integrate) to unity. Usually, basis sets are
|
|
given a combination of normalized primitives, so the normalization
|
|
coefficients of the primitives, $f_{ks}$, need also to be provided.
|
|
|
|
Atomic orbitals (AOs) are defined as
|
|
|
|
\[
|
|
\chi_i (\mathbf{r}) = \mathcal{M}_i\, P_{\eta(i)}(\mathbf{r})\, R_{\theta(i)} (\mathbf{r})
|
|
\]
|
|
|
|
where $\theta(i)$ returns the shell on which the AO is expanded, and
|
|
$\eta(i)$ denotes which angular function is chosen and $P$ are the
|
|
generating functions of the given angular momentum $\eta(i)$. Here,
|
|
the parameter $\mathcal{M}_i$ is an extra parameter which allows the
|
|
normalization of the different functions of the same shell to be
|
|
different, as in GAMESS for example.
|
|
|
|
In this section we describe first how the basis set is stored in the
|
|
context, and then we present the kernels used to compute the values,
|
|
gradients and Laplacian of the atomic basis functions.

*** After initialization
|
|
|
|
When the basis set is completely entered, extra data structures may be
|
|
computed to accelerate the calculations. The primitives within each
|
|
contraction are sorted in ascending order of their exponents, such
|
|
that as soon as a primitive is zero all the following functions
|
|
vanish. Also, it is possible to compute a nuclear radius beyond which
|
|
all the primitives are zero up to the numerical accuracy defined in
|
|
the context.

* Polynomial part
|
|
|
|
Going from the atomic basis set to AOs implies a systematic
|
|
construction of all the angular functions of each shell. We
|
|
consider two cases for the angular functions: the real-valued
|
|
spherical harmonics, and the polynomials in Cartesian coordinates.
|
|
In the case of spherical harmonics, the AOs are ordered in
|
|
increasing magnetic quantum number ($-l \le m \le l$), and in the
|
|
case of polynomials we choose the canonical ordering, i.e
|
|
|
|
\begin{eqnarray}
|
|
p & : & p_x, p_y, p_z \nonumber \\
|
|
d & : & d_{xx}, d_{xy}, d_{xz}, d_{yy}, d_{yz}, d_{zz} \nonumber \\
|
|
f & : & f_{xxx}, f_{xxy}, f_{xxz}, f_{xyy}, f_{xyz}, f_{xzz}, f_{yyy}, f_{yyz}, f_{yzz}, f_{zzz} \nonumber \\
|
|
{\rm etc.} \nonumber
