The author obtained the equations of wave functions to the cubic hybridization (d3fsp3) by using no habitual matematic calculations.It's bases only on the aplication of the usually regels of Quantun Mecanics envolving the Principle of hybrid orbitals construction. Which is possible because the high symmetry (Oh) of this hybridization and because all atomic orbitals envolved are equidistand from the center of the hybrid structure proposed.
