The Energies of Atomic Orbitals03:21

The Energies of Atomic Orbitals

31.5K
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.

¹H NMR: Pople Notation

2.9K
The Pople nomenclature system classifies spin systems based on the difference between their chemical shifts. Coupled spins are denoted by capital letters with subscripts indicating the number of equivalent nuclei. When the coupled nuclei have well-separated chemical shifts, they are assigned letters that are far apart in the alphabet, such as A and X. When the difference in chemical shifts is small, coupled nuclei are named using adjacent letters of the alphabet (AB, MN, or XY).

Atomic Orbitals

47.7K
An atomic orbital represents the three-dimensional regions in an atom where an electron has the highest probability to reside. The radial distribution function indicates the total probability of finding an electron within the thin shell at a distance r from the nucleus. The atomic orbitals have distinct shapes which are determined by l, the angular momentum quantum number. The orbitals are often drawn with a boundary surface, enclosing densest regions of the cloud.

Nuclear Overhauser Enhancement (NOE)01:06

Nuclear Overhauser Enhancement (NOE)

1.7K
Irradiation of a spin-active nucleus causes an increase or decrease in the signal intensity of neighboring nuclei that are not necessarily chemically bonded or involved in J-coupling. This phenomenon, called the nuclear Overhauser enhancement (NOE), results from through-space interactions between the nuclear spins. The NOE effect decreases with increasing internuclear distance and is generally not observed beyond 4 angstroms. In NOE, dipole-dipole interactions between neighboring spin-active...

Nuclear Stability03:18

Nuclear Stability

24.7K
Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters.

Atomic Nuclei: Nuclear Spin State Overview01:03

Atomic Nuclei: Nuclear Spin State Overview

2.3K
NMR-active nuclei have energy levels called 'spin states' that are associated with the orientations of their nuclear magnetic moments. In the absence of a magnetic field, the nuclear magnetic moments are randomly oriented, and the spin states are degenerate. When an external magnetic field is applied, the spin states have only 2 + 1 orientations available to them. A proton with = ½ has two available orientations. Similarly, for a quadrupolar nucleus with a nuclear spin value of one, the...

Area of Science:

  • Nuclear Physics
  • Quantum Chromodynamics
  • Particle Physics

Background:

  • Hypernuclei, atomic nuclei containing hyperons, are crucial for understanding the strong nuclear force.
  • Ab initio calculations are essential for accurately modeling complex nuclear systems.

Purpose of the Study:

  • To conduct the first ab initio calculations for p-shell single-Lambda hypernuclei.
  • To develop and validate theoretical models for hypernuclear structure and interactions.

Main Methods:

  • Utilized two variants of the no-core shell model, incorporating explicit Lambda and Sigma hyperons.
  • Employed chiral two- and three-nucleon interactions, alongside leading-order chiral and meson-exchange hyperon-nucleon interactions.
  • Applied similarity renormalization group transformations to enhance model-space convergence.

Main Results:

  • Validated the theoretical approach using s-shell hypernuclei.
  • Calculated ground-state and excitation energies for p-shell hypernuclei, including 7Li, 9Be, and 13C.
  • Demonstrated agreement between calculated and experimental energies within cutoff dependence.

Conclusions:

  • Chiral hyperon-nucleon interactions show good agreement with experimental data for hypernuclear systems.
  • Hypernuclear spectroscopy provides stringent constraints for refining hyperon-nucleon interaction models.
