** Re^2: Coulomb integrals in the basis of molecular orbitals **
Dmitry

dmitry.ryndyk@physik.uni-regensburg.de

Hallo,I need matrix elements of the Coulomb operator $1/|r-r'|$ for 4 arbitrary molecular wave functions.

In the moment I can calculate Coulomb and exchange integrals for 2 arbitrary functions using localization run with "local=ruednbrg", but possibly it is easier way.

Sincerely,

Dmitry
