Carbon-centered radicals, produced in a chemical-ionization plasma by ion-electron recombination, are trapped in a fast gas-phase reaction with tetracyanoquinodimethan and the products of this reaction, after ionization by electron capture, are analyzed, uzing mass selected collisional activation mass spectrometry.The structures of the ions at the instant of neutralization, 10^-5-10^-4 s after formation, are determined from the collisional activation results.Isomerization occurring in selected nH_{2n-1^{>+, n}}H2n+1^{>+, and nH}n+(n-7)>⁺ ions, n<9, have been delineated and the results compared to previously published gas-phase and/or solution results.
