Charge inversion reaction

Charge-inversion reaction. An ion/neutral reaction wherein the charge on the reactant ion is reversed in sign. 

Other types of reactions have been studied in collisional conditions, especially charge-inversion reactions.

Numerous processes may be linked to proton transfer and protonation/deprotonation reactions (for general descriptions of proton transfer see, for instance, [8.214-8.217]). Proton-triggered yes/no or +/- switching is contained in the ability of polyamine receptors and carriers to bind and transport cations when unproton-ated and anions when protonated also, zwitterions such as amino acids may change from bound to unbound or vice versa, when they undergo charge inversion as a function of pH. 

In the case of the p-p reaction, if the tunnelling operation is successful, an unstable nuclide consisting of 2 protons is created. What can happen next is that either the inverse reaction occurs (one proton escapes from the nucleus) or else one proton quickly releases a positron to remove excess electric charge, and a neutrino to conserve momentum and lepton number, and becomes a neutron thus forming a deuterium nucleus. 

Hydration in homogenous medium is viewed as a process of intermo-lecular orientation interaction of components with H O dipoles. Its inverse reaction is dehydration. These complex processes include into themselves sequential attaching of several H O dipoles to charged particles, sometimes with the replacement of ions tied with them. 

Fig. 4. Strength distribution (matrix-element squared) for the RO matrix element Ml connecting excited states of " T1 to the 0" ground state of ° Pb. The theoretical distribution has been folded with a Gaussian for ease of viewing and to simulate the experimental resolution which might pertain for the inverse charge-exchange reaction. The dominant n-v transition is indicated for the major structures.
