Web31 de ago. de 2024 · For reasons similar to those outlined in the section on ion-dipole forces (11.2), the attractive interactions dominate the repulsive because the attraction causes them to be closer together, which increases the Coulombic interactions. Likewise, the repulsions mean they move farther away, which reduces the Coulombic interactions. Web26 de nov. de 2024 · Coulombic interaction: This strong, short range repulsive force arises from electrostatic repulsion by the electron clouds of the tip and sample. This repulsion increases as the separation decreases. Van der Waals interactions: These are longer range attractive forces, which may be felt at separations of up to 10 nm or more.
