Negative ion-molecule reactions in formic acid.

Hydrothermal Reactions of Formic Acid: Free-Energy Analysis of Equilibrium

The chemical equilibria concerning formic acid are computationally investigated in water over a wide range of thermodynamic conditions. The solvation free energies for relevant C1 compounds are evaluated in the method of energy representation, and are used to assess the solvent effect on the formic acid reactions. In the two competitive decomposition processes of formic acid, the solvent strong...

Adiabatic and diabatic invariants in ion-molecule reactions.

A point charge interacting with a dipole (either induced or permanent) constitutes a completely integrable dynamical subsystem characterized by three first integrals of the motion (E, p(phi), and either l(2) or a Hamilton-Jacobi separation constant beta). An ion-molecule reaction (capture or fragmentation) can be seen as an interaction between such a subsystem and a bath of oscillators. This in...

Ion-molecule reactions reveal facile radical migration in peptides.

Ion-molecule reactions between molecular oxygen and peptide radicals in the gas phase demonstrate that radical migration occurs easily within large biomolecules without addition of collisional activation energy.

State-selected ion-molecule reactions: Statistical calculations with constraints

For the two reactive systems, NH 3 ϩ (E int)ϩN H 3 →NH 4 ϩ ϩNH 2 and H 2 ϩ (E int)ϩH 2 →H 3 ϩ ϩH, for which the relative cross sections were measured earlier in our group for E c.m. Ϸ40 meV we calculated the relative cross section as a function of internal energy using the statistical Rice– Ramsperger–Kassel–Marcus ͑RRKM͒ theory that implicitly conserves total energy and total angular momentum. W...
