Intermolecular forces - interaction between molecules, including forces of attraction or repulsion which act between molecules and other types of neighboring particles, e.g., atoms or ions.
intramolecular force- any force that holds together the atoms making up a molecule or compound. This includes all types of chemical bonds. They are usually stronger than intermolecular forces, which are present between atoms or molecules that are not bonded.
