¹H NMR of Conformationally Flexible Molecules: Temporal Resolution00:52

¹H NMR of Conformationally Flexible Molecules: Temporal Resolution

830
At room temperature, the chair conformer of cyclohexane undergoes rapid ring flipping between two equivalent chair conformers at a rate of approximately 105 times per second. These two chair conformers are in equilibrium. The rapid ring flipping results in the interconversion of the axial proton to an equatorial proton and an equatorial to the axial proton. Such interconversions are too rapid and cannot be detected on the NMR timescale. Hence, the NMR spectrometer cannot distinguish between the...

Intermolecular Forces03:13

Intermolecular Forces

58.2K
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...

Intermolecular vs Intramolecular Forces

87.2K
Intermolecular forces (IMF) are electrostatic attractions arising from charge-charge interactions between molecules. The strength of the intermolecular force is influenced by the distance of separation between molecules. The forces significantly affect the interactions in solids and liquids, where the molecules are close together. In gases, IMFs become important only under high-pressure conditions (due to the proximity of gas molecules). Intermolecular forces dictate the physical properties of...

Intermolecular Forces in Solutions

The formation of a solution is an example of a spontaneous process, a process that occurs under specified conditions without energy from some external source.
When the strengths of the intermolecular forces of attraction between solute and solvent species in a solution are no different than those present in the separated components, the solution is formed with no accompanying energy change. Such a solution is called an ideal solution. A mixture of ideal gases (or gases such as helium and argon,...

Real Gases: Effects of Intermolecular Forces and Molecular Volume Deriving Van der Waals Equation

34.6K
Thus far, the ideal gas law, PV = nRT, has been applied to a variety of different types of problems, ranging from reaction stoichiometry and empirical and molecular formula problems to determining the density and molar mass of a gas. However, the behavior of a gas is often non-ideal, meaning that the observed relationships between its pressure, volume, and temperature are not accurately described by the gas laws.

Van der Waals Interactions01:24

Van der Waals Interactions

63.8K
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.

Area of Science:

  • Physical Chemistry
  • Molecular Dynamics
  • Quantum Mechanics

Background:

  • Molecular rotational dynamics are sensitive to intermolecular interactions.
  • Probing these interactions is crucial for understanding gas-phase chemistry.
  • Environmental effects can significantly influence molecular behavior.

Purpose of the Study:

  • To real-time track laser-driven rotational dynamics of a single nitrogen (N2) molecule.
  • To investigate the influence of neighboring argon (Ar) atoms on N2 rotational dynamics.
  • To probe intermolecular interactions and environmental effects at the molecular level.

Main Methods:

  • Utilized coincident Coulomb explosion imaging to monitor molecular rotational dynamics.
  • Employed time-dependent Schrödinger equation to model observed phenomena.
  • Considered the interaction potential between N2 and Ar atoms.

Main Results:

  • Observed a rapid decay in the N-N axis alignment of N2 within picoseconds when an Ar atom is nearby.
  • Found that the decay rate is dependent on the geometric orientation of the Ar atom relative to the N2 rotational plane.
  • Detected excitation of the van der Waals bond vibration coupled to the N2 rotational axis.

Conclusions:

  • Demonstrated that proximity to Ar atoms significantly perturbs the rotational dynamics of N2.
  • Highlighted the influence of molecular environment on rotational motion and intermolecular forces.
  • Confirmed the capability of visualizing molecular rotational dynamics to probe environmental effects.
