Intermolecular Forces

73.5K
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...

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...

Summary

Thiocyanate anion (SCN-) strongly binds to cationic surfactant head groups in micelles. Its spectral dynamics reveal insights into interfacial hydration, unaffected by micelle size or competitive anions.

Area of Science:

  • Physical Chemistry
  • Supramolecular Chemistry
  • Spectroscopy

Background:

  • Micelles are crucial self-assembled structures in chemistry and biology.
  • Understanding interfacial properties of micelles is key to their applications.
  • The Hofmeister series describes ion-specific effects on these properties.

Purpose of the Study:

  • To investigate the interaction of thiocyanate anion (SCN-) with cationic dodecyltrimethylammonium bromide (DTAB) micelles.
  • To probe interfacial hydration dynamics at cationic interfaces using SCN- as a vibrational probe.
  • To determine the influence of micelle size and interfacial curvature on SCN- dynamics.

Main Methods:

  • Infrared (IR) spectroscopy and Nuclear Magnetic Resonance (NMR) spectroscopy.
  • Ultrafast 2D-Infrared (2D-IR) spectroscopy.
  • Studied SCN- in normal-phase and reverse DTAB micelles of varying sizes.

Main Results:

  • SCN- strongly associates with the cationic head groups of DTAB micelles.
  • No displacement of SCN- by chloride or iodide ions was observed, supporting chaotropic behavior.
  • Spectral diffusion of SCN- was ~3.5 times slower in micelles than in bulk water.
  • No significant dependence on micelle size or interfacial curvature was found.

Conclusions:

  • SCN- serves as a robust probe for interfacial hydration at cationic interfaces.
  • The observed slowdown in dynamics is attributed to excluded volume effects and hydration.
  • SCN- exhibits strong association with head groups, partially buried within the micelle structure.
