intermolecular

Across molecular boundaries

Intermolecular describes forces or interactions occurring between separate molecules rather than within a single molecule.

These forces—like hydrogen bonding and van der Waals attractions—determine physical properties such as boiling point and viscosity: Intermolecular forces in water account for its unusually high surface tension.

The term contrasts with intramolecular, which refers to forces within a molecule.
