They are also properly normalized in the same step. Thus all operator matrices like the Kohn-Sham matrix, the overlap matrix, and the wavefunctions (MOs) are represented using spherical Gaussian functions. This representation is also used by the wavefunction optimization (SCF) and determines the available degrees of freedom for the solver during the optimization which causes eventually the difference between a spherical and a Cartesian Gaussian basis set.<o:p></o:p> <o:p> </o:p> HTH<o:p></o:p> <o:p> </o:p> Matthias<o:p></o:p> <o:p> </o:p> From: cp...@googlegroups.com <...@googlegroups.com> On Behalf Of Lucas Lodeiro Sent: Donnerstag, 24.

You and the CP2K paper mention that only spherical functions are used, but in the output (with the same input of the first message, justo with print_level medium) shows that 6 d functions are used for oxygen. CP2K internally transforms those 6 cartesian functions in the spherical ones? There is another "change" respect the ATOMIC KIND INFORMATION printed in the output?<o:p></o:p> </div> <div> <o:p> </o:p> </div> <div> Regards - Lucas Lodeiro<o:p></o:p> </div> <div> <o:p> </o:p> </div> <div> ******************************************************************************************************************<o:p></o:p> </div> <div> ATOMIC KIND INFORMATION 1.
