Figure shows a selection of condensed property fields as contours mapped onto the atoms of ethylene. The top, middle, and bottom rows respectively show condensed properties from each category. Starting with the condensed scalar fields (category A; top row), in organic systems the condensed density (𝒫) seems to correlate with the topology of the condensed kinetic energy (𝒯) and volume (𝒱), that is, they typically have the same sets of maximum, minimum, and saddle CPs . Thus, in many systems, bond bundles, defined according to 𝒫 (see the red paths on the spheres in Figure ), wouldn't differ dramatically if defined according to another condensed scalar property such as kinetic energy density.
