Intermolecular vs Intramolecular Forces

101.4K
Intermolecular forces (IMF) are electrostatic attractions arising from charge-charge interactions between molecules. The strength of the intermolecular force is influenced by the distance of separation between molecules. The forces significantly affect the interactions in solids and liquids, where the molecules are close together. In gases, IMFs become important only under high-pressure conditions (due to the proximity of gas molecules). Intermolecular forces dictate the physical properties of...

Intermolecular Forces

76.0K
Atoms and molecules interact through bonds (or forces): intramolecular and intermolecular. The forces are electrostatic as they arise from interactions (attractive or repulsive) between charged species (permanent, partial, or temporary charges) and exist with varying strengths between ions, polar, nonpolar, and neutral molecules. The different types of intermolecular forces are ion–dipole, dipole–dipole, hydrogen bonds, and dispersion; among these, dipole–dipole, hydrogen...

Van der Waals Interactions

72.9K
Atoms and molecules interact with each other through intermolecular forces. These electrostatic forces arise from attractive or repulsive interactions between particles with permanent, partial, or temporary charges. The intermolecular forces between neutral atoms and molecules are ion–dipole, dipole–dipole, and dispersion forces, collectively known as van der Waals forces.

Intermolecular Forces in Solutions

40.7K
The formation of a solution is an example of a spontaneous process, a process that occurs under specified conditions without energy from some external source.
When the strengths of the intermolecular forces of attraction between solute and solvent species in a solution are no different than those present in the separated components, the solution is formed with no accompanying energy change. Such a solution is called an ideal solution. A mixture of ideal gases (or gases such as helium and argon,...

    Area of Science:

    • Surface Science
    • Molecular Interactions
    • Nanoscale Chemistry

    Background:

    • Nickel-phthalocyanine molecules (NiPCs) exhibit intermolecular repulsion when physisorbed on Au(111) due to induced charge dipole moments.
    • Understanding and controlling molecular interactions at surfaces is crucial for nanoscale device fabrication.

    Purpose of the Study:

    • To investigate the local modification of intermolecular interactions in NiPCs on an Au(111) substrate.
    • To elucidate the mechanism behind attraction between NiPCs upon chemisorption.
    • To demonstrate control over NiPC desorption based on surface density.

    Main Methods:

    • Scanning tunneling microscopy (STM) for real-space observation of molecular behavior.
    • Bias pulse application to induce chemisorption via ligand dehydrogenation.
    • Density functional theory (DFT) calculations to model charge redistribution and interactions.

    Main Results:

    • Physisorbed NiPCs repel each other.
    • Chemisorption of one NiPC via dehydrogenation induces attraction towards a nearby physisorbed NiPC.
    • This attraction is attributed to local charge redistribution around the dehydrogenated ligand.
    • Desorption of the attracted NiPC is controllable by adjusting the local NiPC density.

    Conclusions:

    • Chemisorption fundamentally alters NiPC intermolecular interactions, enabling controlled molecular trapping.
    • Local charge redistribution is the key mechanism driving the observed attraction.
    • Surface density offers a tunable parameter for controlling molecular desorption and assembly.
