The last observed phenomenon, the emergence of circular current from helical MOs, is most clearly seen in Figure and the two contributions of the rightmost column of Figure 9. To explain this phenomenon, we start by looking at ∇ψa in the left column of Figure . As we explained earlier, the circular component of the gradient field is already notable as seen by the blue and red arrows that cluster along the nodal planes. We also explained that the MO, ψ b , emphasizes the region of space that the circular current density occupies. Importantly, because ψ b is guaranteed by symme-try to have opposite chirality compared with ψa, ψ b will not suppress all the regions where ∇ψa has a high density of arrows. The result of this can be seen in the rightmost column of Figure . Ultimately, the circular current arises from the gradient across a nodal plane, but is not inherently tied to the helicality of the MO. Although the circular current manifests from the gradient across a nodal plane, it is not intrinsically linked to the helical nature of the MO. The helical MO serves to facilitate the propagation of the circular current from the gradient field to the current density. However, it is not directly responsible for the circular current density itself. Rather, the combined action of the two MOs, their respective chiralities, and their interaction with nodal planes and gradients contribute to this unique phenomenon of circular current density.
