To heed another aspect of these wave functions that might be conventionally overlooked, consistent with Heisenberg's focus on the spectral properties of an atom, we calculate the intensity of a spectral transition, from the electronic ground state, that is proportional to the squared matrix element involving the electric dipolar (or other) moment as operator, which we express in two forms, taking cartesian coordinate z = r cos([theta]) as the direction of both the dipolar moment of the transition and the electric vector of an electromagnetic wave incident on the atom.
