## Abstract A modified Gaussian function __g__(__u__, __v__, __w__, __a__, **__R__**) = const equation image __s__(__a__, **__R__**) is considered where __l__ = __u__ + __v__ + __w__, __s__ (__a__, **__R__**) is a 1__s__‐type Gaussian function centered at **R**, __a__ is the coefficient in the ex

Abstract
The general formula for the electron‐electron repulsion integral in the modified Cartesian Gaussian basis set derived in Ref. [1] is simplified. A general relation between the standard and modified CG functions is given. A possible use of the modified CG functions to quantum chemical calculations which include the correlation factor r~ij~^2^ is indicated.

It is demonstrated that variational calculations based on explicitly correlated Gaussian functions for the hydrogen molecule in its ground state lead to energies of the same level of accuracy as those based on the Kotos-Wolniewicz functions. The energies obtained are the lowest reported so far, in c
## Abstract A major unresolved problem of density functional theory is the yet unknown exchange‐correlation functional, which leads to a proliferation of its less or more successful approximations. A practical implementation of these numerous functionals can present a substantial challenge particul
