Two-Dimensional (2D) NMR: Overview

631
The 1D NMR spectrum of large and complex molecules like natural products has complicated splitting patterns and overlapping signals, which can be easily interpreted using 2-dimensional (2D) NMR. Unlike 1D NMR, 2D NMR has two frequency axes that provide the coupling information between the nucleus A and nucleus B in a molecule. The process from which 2D spectra are obtained has four steps.
The first step is the preparation period, during which nucleus A is excited with a radiofrequency pulse....

Molecular Spectroscopy: Absorption and Emission

1.9K
Molecules possess discrete energy levels called quantum states. Unlike atoms, which have simpler energy levels, molecules possess additional rotational and vibrational energy levels.  Each energy level is separated by an energy gap, with the gaps between adjacent electronic, vibrational, and rotational levels varying significantly. The three types of energy levels in a diatomic molecule are shown in Figure 1.

In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

Area of Science:

  • Quantum optics and photonics
  • Materials science for quantum applications
  • Computational condensed matter physics

Background:

  • Nonclassical states of light are essential for quantum technologies.
  • Organic molecules on substrates are promising for single-photon generation due to scalability and tunable emission.
  • Previous research focused on color centers in insulators, but organic systems offer advantages.

Purpose of the Study:

  • To investigate photoemission from organic molecules adsorbed on 2D materials using first-principles calculations.
  • To understand the role of substrate interactions in shaping molecular optical properties.
  • To provide insights for designing molecular systems for quantum applications.

Main Methods:

  • First-principles calculations (e.g., density functional theory).
  • Modeling of terrylene molecules adsorbed on hexagonal boron nitride (hBN).
  • Analysis of photoemission spectra, including zero phonon line (ZPL) energies and lineshapes.

Main Results:

  • Calculated ZPL energies and emission lineshapes for terrylene on hBN agree well with experimental data.
  • Antisite defects in hBN can immobilize molecules without altering their primary emission characteristics.
  • The 2D substrate introduces sharp sidebands near the ZPL, indicative of hindered molecular motion (rotational, translational, bending).

Conclusions:

  • Substrate interactions significantly influence the optical properties of adsorbed organic molecules.
  • Hexagonal boron nitride is a suitable substrate for immobilizing organic emitters without compromising their quantum emission.
  • Understanding these substrate-molecule interactions is key to advancing molecular quantum technologies.
