Van der Waals Interactions01:24

Van der Waals Interactions

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 Forces03:13

Intermolecular Forces

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 bonds, and dispersion...

Molecular Shapes01:18

Molecular Shapes

Molecules have characteristic shapes that are crucial for their function. The arrangement of various electron groups around the central atom dictates their molecular geometry. Electron pairs in the valence shell of a central atom will adopt an arrangement that minimizes repulsions between the electron pairs by maximizing the distance between them. The valence electrons form either bonding pairs, located primarily between bonded atoms, or lone pairs.

¹H NMR: Long-Range Coupling01:27

¹H NMR: Long-Range Coupling

The coupling interactions of nuclei across four or more bonds are usually weak, with J values less than 1 Hz. While these are usually not observed in spectra, the presence of multiple bonds along the coupling pathway can result in observable long-range coupling.
In alkenes, spin information is communicated via σ–π overlap, as seen in allylic (four-bond) and homoallylic (five-bond) couplings. These coupling interactions are stronger when the σ bond is parallel to the alkene π orbitals.
Resonance and Hybrid Structures02:16

Resonance and Hybrid Structures

According to the theory of resonance, if two or more Lewis structures with the same arrangement of atoms can be written for a molecule, ion, or radical, the actual distribution of electrons is an average of that shown by the various Lewis structures.
Resonance Structures and Resonance Hybrids
The Lewis structure of a nitrite anion (NO2−) may actually be drawn in two different ways, distinguished by the locations of the N–O and N=O bonds.

Area of Science:

  • Condensed Matter Physics
  • Materials Science
  • Statistical Mechanics

Background:

  • Many-particle systems exhibit complex behaviors governed by their energy landscapes.
  • Stealthy and hyperuniform states possess unique scattering and density fluctuation properties.

  • Cooling and quenching simulation techniques to generate inherent structures.
  • Quantitative metrics to assess stealthiness and hyperuniformity.
  • Nudged-elastic-band algorithm to map transition pathways between configurations.
  • Analysis of point patterns from random sequential addition (RSA) of hard disks.

Main Results:

  • Inherent structures exhibit tunable stealthiness and hyperuniformity based on constrained degrees of freedom (χ).
  • These structures commonly feature five-particle rings, wavy grain boundaries, and defects.
  • Structural and thermodynamic properties showed insensitivity to sampling temperature, indicating a flat energy landscape.
  • Small, collective particle rearrangements are sufficient to transform nearly stealthy RSA configurations into absolutely stealthy states.

Conclusions:

  • The k-space overlap potential generates stealthy and hyperuniform inherent structures in 2D systems.
  • The degree of stealthiness and hyperuniformity can be controlled by system constraints.
  • The energy landscape is characterized by wide, shallow minima, facilitating transitions.
