Recombination, electron-ion

CHXNH. Many of the reactions involve radiative association. Dissociative electron-ion recombination then yields neutrals such as CH (methane), C2H OH (ethanol) and CH CN (acetonitrile) [158]. It is often joked... 

In deriving the kinetic equation describing the arrival of various ionic species at the cathode, it is assumed that the primary species N2 + is formed at the central wire at a constant rate, and during its passage in the direction x perpendicular to the axis its concentration is modified by various reactions. In this treatment both ion diffusion and ion-ion or electron-ion recombination processes are neglected because the geometry of the discharge tube and the presence of an electric field would... 

COMPLEX FORMATION IN ELECTRON-ION RECOMBINATION OF MOLECULAR IONS... 

Our discussion of complex formation in electron-ion recombination, field effects, and three-body recombination has perhaps posed more questions than it has answered. In the case of H3 recombination, the experimental observations suggest but do not prove that complex formation is an important mechanism. Three-body recombination involving complex formation is not likely to have much effect on the total recombination coefficients of diatomic ions, but it may alter the yield of minor product channels. Complex formation may be most prevalent in the case of large polyatomic ions, but there is a serious lack of experimental data and theoretical calculations that can be adduced for or against complex formation. 

This isomeric form is of interest from an interstellar point of view since the isomer, CH3OH2, is a possible route, via dissociative electron-ion recombination, to the observed methanol.14 A proposed reaction68 leading to this isomer is the radiative association,... 

There has been a consistent motivation for the work presented in this chapter the application to molecular synthesis in interstellar gas clouds (see, for example, Herbst,22 this volume). The species in these regions are detected spectroscopically and are thus automatically isomerically identified. The routes to the observed neutral species consistently involve ion-molecule reactions followed by dissociative electron-ion recombination.18 The first step in this process is to determine whether an isomeric ion can be formed which is likely to recombine to an observed neutral species. The foregoing discussion has shown that whether this occurs depends on the detailed nature of the potential surface. Certainly, this only occurs in some of the cases studied. Much more understanding will be required before the needs of this application are fulfilled.

Kinetics of Electron-Ion Recombination in Irradiated Dielectric Liquids... 

A great deal of work has been done by Hummel and co-workers on electron-ion recombination in hydrocarbon liquids using random flight MC simulation. This will be discussed in Sect. 7.5. 

KINETICS OF ELECTRON-ION RECOMBINATION IN IRRADIATED DIELECTRIC LIQUIDS3... 

Rzad et al. (1970) obtained the relative lifetime distribution of electron-ion recombination in cyclohexane by 1LT of Eq. (7.26). Denoting the probability that the lifetime would be between t and t + dt as f(t) dt, the thusly defined scavenging function at scavenger concentration c% is given by...
