IR and UV–Vis Spectroscopy of Carboxylic Acids01:28

IR and UV–Vis Spectroscopy of Carboxylic Acids

In IR spectroscopy of carboxylic acids, the C=O bond shows a characteristic band between 1710 and 1760 cm⁻¹, and the O–H bond exhibits a broad band between 2500 and 3300 cm⁻¹.
However, the stretching absorptions for the C=O bond vary depending on the structure of carboxylic acids. The C=O bond of the free carboxylic acids shows a higher stretching frequency, 1760 cm−1, while H-bonded carboxylic acids (dimers) exhibit stretching absorptions at a lower frequency, 1710 cm−1. The C=O bond of the...

Polymer Classification: Crystallinity

Unlike ionic or small covalent molecules, polymers do not form crystalline solids due to the diffusion limitations of their long-chain structures. However, polymers contain microscopic crystalline domains separated by amorphous domains.
Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...

Area of Science:

  • Spectroscopy
  • Polymer Science
  • Physical Chemistry

Background:

  • Understanding water's state in polymers is crucial for material properties.
  • Poly(2-methoxyethyl acrylate) (PMEA) exhibits complex water interactions.
  • Mid-infrared spectroscopy offers insights into hydrogen bonding and water structures.

Purpose of the Study:

  • To characterize cold-crystallizable water sorbed in PMEA.
  • To investigate the influence of water content (WC) on water's spectral signature.
  • To explore the thermal behavior and phase transitions of sorbed water.

Main Methods:

  • Multicomponent analysis of mid-infrared spectra.
  • Phenomenological decomposition of the O-H stretching band into Voigt components.
  • Thermal cycling and fixed-basis regression to analyze spectral changes.

Main Results:

  • Increasing WC linearly increases spectral band area and shifts weight from polymer-hydrated to water-water associated components.
  • Low WC shows reversible water redistribution upon thermal cycling without ice signatures.
  • An ice Ih-like contribution appears only upon heating at higher WC (3.30 wt %), with a crossover around 215 K.

Conclusions:

  • Water reorganization in PMEA is mobility-controlled and coupled to polymer dynamics.
  • The ice Ih contribution below 273 K suggests interfacial dissolution and redistribution rather than bulk melting.
  • Spectroscopic analysis reveals distinct water states and transitions dependent on water content and temperature.
