Equation 24 shows that, the current density is a sum over orbital-gradient pairs, ψi(r)∇ψj(r), with G < ij (E) scaling how much each pair contributes to the overall current density. Therefore, it is straightforward to partition the current density into contributions that are closer to our chemical intuition. For example, we can choose to only look at the contributions from a subset of orbitals, for example: AOs of the same type, such as p-orbitals; individual MOs, such as the highest occupied MO (HOMO); or the full σ-system. We will use these types of subdivisions to explain how the current density manifests in the three model systems.
