There are different types of attractive forces that exist between atoms and molecules. Some are classified as bonds (ionic, covalent, metallic) as they involve the sharing or exchange of valence electrons. Others are simply attractive forces between one molecule and another but do not involve...
Three types of intermolecular interactions are considered: van der Waals (vdW), donoracceptor and hydrogen bonds. Are vdW forces caused by instantaneous dipoles created by electrons’ orbiting the nuclei (London)—or by accumulation of electron density between atoms (Feynman, later Bader), broadly s...
By the end of this section, you will be able to: Describe the types of intermolecular forces possible between atoms or molecules in condensed phases (dispersion forces, dipole-dipole attractions, and hydrogen bonding) Identify the types of intermolecular forces experienced by specific molecules based...
If the solvent–polymer interaction is equal to that of the intermolecular interaction, then an ideal solution will be obtained. For the electrospinning of polymer solution, there must be a sufficient degree of intermolecular interaction to undergo the drawing forces during the process....

of the external electric fieldEin energy and force calculations in Tinker, we introduced into the code the electric force term\(F = k_1qE\)and induced-dipole term\(\mu = k_2\alpha E\), whereqis the atomic charge. The constantsk1 = 1,185.85 andk2 = 3.567 give the forces ...
The effect of the chemical bond character (the degrees of covalenceCc, metallicityCm, and ionicityCi) on the bond rigidity and the components of the van der Waals intermolecular interaction have been shown for halogens and hydrogen halides as an example. The force constant is determined by the...
