The use of molecular orbitals (MOs) to qualitatively predict and explain chemical reactivity and physical phenomena is ubiquitous. Despite being a mathematical construct rather than a physical observable, MOs have nonetheless been successfully used to explain and predict physical effects. One interesting quantity that is calculated as an interaction between all MOs is the current density, and a variety of methods have been developed to calculate it through molecular junctions. It is a tool that provides spatial information about how the current flows through a molecular junction at a particular bias, meaning we can probe how the electronic properties of a molecular system change as a function of position in the molecule. A better understanding of the current density will also enable us to make more accurate predictions about the magnetic fields that will inevitably be created. In prior work, it has been noted that the current density through molecules sometimes seems to be at odds with our chemical intuition. In graphene and unsaturated polyenes, the current density has a nodal plane that spans the same plane as the molecule, where the current density goes to ≈ 0. We show an example of this in Fig- . At first, this seems to make intuitive sense as it is the same nodal plane that exists in all the π-MOs, however, no such clear relationship exists between MOs and current density for other systems, raising the question of why this is the case for these systems? In alkanes, the current density seems to take the shortest path through the molecules, ignoring the zigzag path outlined by the σ-bonds. This pattern is preserved when moving to silanes and germanes, and seems to suggest that bonds are not a good predictor for where the current will flow. We show an example of this current density in butane in Figure .
