Phase Transitions: Melting and Freezing02:39

Phase Transitions: Melting and Freezing

12.6K
Heating a crystalline solid increases the average energy of its atoms, molecules, or ions, and the solid gets hotter. At some point, the added energy becomes large enough to partially overcome the forces holding the molecules or ions of the solid in their fixed positions, and the solid begins the process of transitioning to the liquid state or melting. At this point, the temperature of the solid stops rising, despite the continual input of heat, and it remains constant until all of the solid is...

Aqueous Solutions and Heats of Hydration

14.8K
Water and other polar molecules are attracted to ions. The electrostatic attraction between an ion and a molecule with a dipole is called an ion-dipole attraction. These attractions play an important role in the dissolution of ionic compounds in water.
When ionic compounds dissolve in water, the ions in the solid separate and disperse uniformly throughout the solution because water molecules surround and solvate the ions, reducing the strong electrostatic forces between them. This process...

States of Water

51.3K
Water exists in any one of the three classical states: solid (ice), liquid (water), and gas (steam or water vapor). The state of water depends on i) the intermolecular forces that draw molecules together and ii) the kinetic energy that leads to movements that pull them apart.
Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...

Heating and Cooling Curves02:44

Heating and Cooling Curves

23.2K
When a substance—isolated from its environment—is subjected to heat changes, corresponding changes in temperature and phase of the substance is observed; this is graphically represented by heating and cooling curves.
For instance, the addition of heat raises the temperature of a solid; the amount of heat absorbed depends on the heat capacity of the solid (q = mcsolidΔT). According to thermochemistry, the relation between the amount of heat absorbed or released by a substance, q, and its...

Polymer Classification: Crystallinity

2.9K
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...

Molecular and Ionic Solids02:54

Molecular and Ionic Solids

17.4K
Crystalline solids are divided into four types: molecular, ionic, metallic, and covalent network based on the type of constituent units and their interparticle interactions.
Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...

Area of Science:

  • Astrochemistry
  • Condensed Matter Physics
  • Materials Science

Background:

  • Amorphous solid water (ASW) is a key component of interstellar and cometary ices, crucial for planetary system formation.
  • Understanding vibrational energy dissipation and structural changes in ASW is vital but remains challenging.
  • The hydrogen-bonding network in ASW is hypothesized to play a critical role in energy transfer and structural dynamics.

Purpose of the Study:

  • To investigate hydrogen-bonding modifications in amorphous solid water (ASW) induced by intense mid-infrared free-electron laser (FEL) radiation.
  • To elucidate the mechanisms of vibrational energy transfer and dissipation within the ASW hydrogen-bonding network.
  • To correlate structural changes with irradiation history and molecular dynamics.

Main Methods:

  • Experimental irradiation of ASW using the FELIX-2 beamline's mid-IR FEL.
  • Monitoring structural changes via reflection-absorption infrared spectroscopy.
  • Confirmation and mechanistic insights through molecular dynamics simulations.

Main Results:

  • FEL irradiation induces local structural changes in ASW due to vibrational energy transfer.
  • Vibrationally excited water molecules can reorient to optimize tetrahedral coordination without breaking hydrogen bonds.
  • Vibrational energy transfer occurs through the hydrogen-bonding network to molecules with similar vibrational frequencies.
  • Energy dissipation is expected to be lower in amorphous compared to crystalline water due to frequency inhomogeneity and defect sites.

Conclusions:

  • The hydrogen-bonding network in ASW facilitates vibrational energy transfer and influences structural dynamics under FEL irradiation.
  • Inhomogeneity and defect sites in ASW's hydrogen-bonding network can impede energy dissipation compared to crystalline ice.
  • These findings enhance our understanding of ice evolution in astrophysical environments and material properties.
