Spontaneous self-ionization in the gas phase: a theoretical prediction
1Departamento de Química, C-9, Universidad Autónoma de Madrid, Cantoblanco, 28049 Madrid, Spain.
Summary
Proton transfer in dimers can occur spontaneously, even within the same functional groups like phosphinic acid derivatives. Substituents can control the interaction strength, ranging from hydrogen bonds to ion pairs.
Area of Science:
- Chemical dynamics
- Molecular interactions
- Supramolecular chemistry
Background:
- Proton transfer is crucial in chemical reactions and biological processes.
- Dimers can exhibit unique reactivity compared to monomers.
- Hydrogen bonding and ion pairing are key intermolecular forces.
Purpose of the Study:
- To investigate spontaneous proton transfer in dimers of phosphinic acid derivatives.
- To explore the role of substituents in modulating dimer interactions.
- To understand the transition between hydrogen-bonded complexes and ion pairs.
Main Methods:
- Computational chemistry methods (e.g., DFT) were likely employed.
- Analysis of potential energy surfaces for proton transfer.
- Spectroscopic techniques could be used for experimental validation.
Main Results:
- Spontaneous self-ionization and proton transfer observed in phosphinic acid derivative dimers.
- Proton transfer occurs even with identical functional groups.
- Tunable interaction strength (hydrogen bond to ion pair) by substituent modification.
Conclusions:
- Phosphinic acid derivatives can undergo self-ionization within dimers.
- Substituent effects offer a mechanism to control dimer interaction types.
- This provides insights into molecular recognition and reaction design.

01:21Chemical Ionization (CI) Mass Spectrometry
The molecular ion peak of a molecule in the mass spectrum provides vital information for molecular identification. However, conventional electron impact ionization can lead to the rapid dissociation of some molecular ions before they reach the detector. A milder ionization method is required to increase the lifetime of such ionized analyte molecules. Chemical ionization (CI) is a gas-phase protonation reaction useful for mass-analyzing analyte molecules that are easily protonated to yield the...
01:12Kinetic Theory of an Ideal Gas
A mole is defined as the amount of any substance that contains as many molecules as there are atoms in exactly 12 grams of carbon-12. An Italian scientist Amedeo Avogadro (1776–1856) formed the hypothesis that equal volumes of gas at equal pressure and temperature contain equal numbers of molecules, independent of the type of gas. Later, the hypothesis was developed to form the SI unit for measuring the amount of any substance.
The number of molecules in one mole is called Avogadro's number...

03:12Ionization Energy
The amount of energy required to remove the most loosely bound electron from a gaseous atom in its ground state is called its first ionization energy (IE1). The first ionization energy for an element, X, is the energy required to form a cation with 1+ charge:
01:23Theory of Strong Electrolytes
The interionic forces of the strong electrolytes depend on the solvent's dielectric constant, which is the ability of a solvent to store electrical energy, based on its polarizability. and the solution's concentration. In high-dielectric solvents and in dilute solutions, weak electrostatic forces keep ions apart. However, in low-dielectric solvents or concentrated solutions, stronger interionic forces may cause ions to pair up as ionic doublets despite being fully ionized. The theory of strong...
04:01Real Gases: Effects of Intermolecular Forces and Molecular Volume Deriving Van der Waals Equation
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.
02:34Kinetic Molecular Theory and Gas Laws Explain Properties of Gas Molecules
The test of the kinetic molecular theory (KMT) and its postulates is its ability to explain and describe the behavior of a gas. The various gas laws (Boyle’s, Charles’s, Gay-Lussac’s, Avogadro’s, and Dalton’s laws) can be derived from the assumptions of the KMT, which have led chemists to believe that the assumptions of the theory accurately represent the properties of gas molecules.
