Net Laboratory of Computational Chemistry

Welcome to
Orbuculum that is Crystall Ball.
It breaks the common chemistry packages' paradigm of Black Box. Here, we give access to calculations' details, like form of the involved orbitals, overlap integrals, further parameters used in calculation... The service is permanently under construction.

Now we have a periodic table in the form (9x18 with blanks). It is to be made clickable so that the element selection is done by a click.

For the time being: Please type in the atomic number (left subscript) of the element for which you want to access information about its MAP basis set:

and press the button.
Otherwise insert atomic numbers for two elements

and press the button to access properties of this pair as derived from their respective MAP basis sets.
