Inspection of the ethylene maximum basin (bond wedge) values in Figure reveals a more intricate relationship between the charge redistribution to, from, and within C atoms. When considering the totality of charge within an atomic basin, the 𝑥-oriented field appears to push charge through C1 from H2 to H3, that is, C1 accepts charge from H2 and donates it to H3, with the charge moving in the -𝑥 direction. However, within the atomic basin C1 shifts charge in the opposite direction, from the C1-H3 bond wedge to the C1-H2 bond wedge, by an amount equal to that transferred to/from the H atoms; ~0.05e gained from H2, ~0.05e given to H3, and ~0.05e shifted from the C1-H3 bond wedge to the C1-H2 bond wedge. The ambiguous case of the 𝑦-field response results in the same behavior. Within both C atoms, the intra-atomic charge redistribution is in the positive y-direction, opposite the direction of inter-atomic redistribution and opposite that expected of an electron gas.
