We explore the impact of vdW polarization density by adding ρ pol (r) to the PBE-calculated density ρ PBE (r), yielding ρ tot (r) = ρ PBE (r) + ρ pol (r). NCI plots show significant changes when vdW polarization is included, as seen in Figure . The gradient isosurfaces reveal how vdW polarization thickens green vdW regions and elongates red steric repulsion zones. Larger systems, such as C3GC (Figure ) and DNA-ellipticine (Figure ), exhibit more connected and continuous vdW isosurfaces, providing a more coherent picture of vdW interactions. Additionally, repulsive regions in π -π systems become more pronounced with MBD polarization, particularly in comparison to the benzene dimer.
