IR Absorption Frequency: Delocalization

1.6K
Electron delocalization refers to the distribution of electrons across multiple atoms within a molecule rather than being confined to a single atom or bond. This phenomenon is common in systems with conjugated bonds—structures where alternating single and double bonds allow π-electrons to move freely across the network. The movement of electrons stabilizes the molecule and can affect various chemical properties, including vibrational frequencies observed in IR spectroscopy.
In IR...

The Energies of Atomic Orbitals

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.

VSEPR Theory

Valence shell electron-pair repulsion theory (VSEPR theory) enables us to predict the molecular structure around a central atom from an examination of the number of bonds and lone electron pairs in its Lewis structure. The VSEPR model assumes that electron pairs in the valence shell of a central atom will adopt an arrangement that minimizes repulsions between these electron pairs by maximizing the distance between them. The electrons in the valence shell of a central atom form either bonding...

Electron Orbital Model

Orbitals are the areas outside of the atomic nucleus where electrons are most likely to reside. They are characterized by different energy levels, shapes, and three-dimensional orientations. The location of electrons is described most generally by a shell or principal energy level, then by a subshell within each shell, and finally, by individual orbitals found within the subshells.
The first shell is closest to the nucleus, and it has only one subshell with a single spherical orbital called the...

π Electron Effects on Chemical Shift: Overview

1.5K
An applied magnetic field causes loosely bound π-electrons in organic molecules to circulate, producing a local or induced diamagnetic field over a large spatial volume. As the molecules tumble in solution, the field generated by π-electrons in spherical substituents results in a zero net field. However, the net field generated by π-electrons in non-spherical substituents is not zero. The effect of this induced field depends on the orientation of the molecule with respect to B0,...

Purpose of the Study:

  • To develop a novel, intuitive approach for quantifying and visualizing electron delocalization in real space.
  • To provide a tool that aids in understanding chemical bonding and reactivity.

Main Methods:

  • Development of the electron delocalization range function, EDR (r⃗;u).
  • EDR quantifies electron delocalization over a specified length scale (u) at a given point (r⃗) in a wavefunction.

Main Results:

  • The EDR function provides physically reasonable predictions, aligning with known electron localization in atomic cores and covalent bonds.
  • Demonstrated EDR's capability to represent atomic shell structure, bonding types, and delocalization in various systems.

Conclusions:

  • The developed EDR function offers a powerful and intuitive method for analyzing electron delocalization.
  • This approach enhances the understanding and prediction of chemical properties and reactivity across diverse chemical systems.
