Summary
Superatoms exhibit potential energy surface (PES) crossing behavior like atoms, but their relative rotation introduces new dimensions. Rotational effects on energy and charge are significant, aiding superatomic material assembly.
Area of Science:
- Computational chemistry
- Materials science
- Quantum mechanics
Background:
- Superatoms are nanoscale building blocks with unique electronic properties.
- Understanding intermolecular interactions is crucial for designing novel materials.
- Atomic potential energy surfaces (PES) describe interactions between atoms.
Purpose of the Study:
- To investigate the potential energy surface between superatoms (SPES).
- To compare SPES behavior with atomic PES.
- To explore the impact of superatom rotation on SPES.
Main Methods:
- First-principles calculations were employed.
- The study analyzed the potential energy surface between two superatoms.
- Rotational effects on energy and charge were quantified.
Main Results:
- Superatoms display SPES crossing behavior analogous to atomic PES.
- Relative rotation between superatoms introduces new dimensions to the SPES.

In an atom, the negatively charged electrons are attracted to the positively charged nucleus. In a multielectron atom, electron-electron repulsions are also observed. The attractive and repulsive forces are dependent on the distance between the particles, as well as the sign and magnitude of the charges on the individual particles. When the charges on the particles are opposite, they attract each other. If both particles have the same charge, they repel each other.

Atoms participate in a chemical bond formation to acquire a completed valence-shell electron configuration similar to that of the noble gas nearest to it in atomic number. Ionic, covalent, and metallic bonds are some of the important types of chemical bonds. Bond energy and bond length determine the strength of a chemical bond.
Types of Chemical Bonds
An ionic bond is formed due to electrostatic attraction between cations and anions. Often, the ions are formed by the transfer of electrons...

Thermodynamic potentials are state functions that are extremely useful in analyzing a thermodynamic system. They have dimensions of energy. The four important thermodynamic potentials are internal energy, enthalpy, Helmholtz free energy, and Gibbs free energy. These thermodynamic potentials can be expressed using two of the following variables: pressure, volume, temperature, and entropy. These two variables are expressed as the rate of change of the thermodynamic potential with respect to other...

Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...

69.1K
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.
