“…The CID and charge reversal (CR) spectra [28][29][30] were recorded with a Fisons ZAB-2HFqQ (Fisons Instruments, Manchester, UK) reverse geometry doublefocusing quadrupole hybrid mass spectrometer [31,32]. The CID experiments were carried out with He as the collision gas, whereas 0 2 was used as the collision gas in the CR experiments.…”

The reactions of the atomic oxygen radical anion O-with CH3--S--CH2--CN m the gas phase have been examined with Fourier transform ion cyclotron resonance in combination with tandem mass spectrometric experiments performed with a double-focusmg quadrupole hybrid mstrument. Deuterium labelmg has revealed that the O-ion reacts with CH3--S--CH2--CN by proton abstraction from the methylene group as well as by competing 1,1-and 1,3-H~ abstractions to afford isomeric radical anions. High kinetic energy (8 keV) collision-induced charge reversal experiments mdicate that the 1,1-H~-'-abstraction leads to a CHB--S--C'--CN carbene ion, whereas the 1,3-H~ abstraction yields a novel sulfur-containing distomc radical anion, wt'uch is formulated as "CH2--S--CH--CN.

“…This instrument allowed for a further characterization of these structures by tandem mass spectrometric techniques. Whereas the CA-MIKE spectra showed only H Á losses, charge reversal ( À CR ) spectra (Bowie & Blumenthal, 1975;Bursey, 1990) were measured and proved to be diagnostic. CR spectra are achieved by the double oxidation of the incident anions under typical high energy CA conditions.…”

“…12 Therefore, provided fragmentation is fast, the major fragments can reflect the original structure of the precursor anion. 24 Most charge inversion experiments have been performed on sector instruments. 25 Albeit early work involved the use of forward geometry sector instruments, most charge inversion experiments have been conducted with reverse geometry sector instruments.…”

“…12 Since then, a variety of work has been conducted. 24 A fundamental application is the measurement of a molecule's electron affinity via determination of the energy loss associated with the inversion reaction, assuming the ionization energy is known. 22,29 Dissociative charge inversion of negative precursor ions has played an important role in ion structure elucidation, particularly when the tandem mass spectrum of the negative precursor ion shows little, if any, fragmentation.…”

Central to the tandem mass spectrometry experiment is the process that gives rise to product ions, i.e. the reaction intermediate to stages of mass analysis. Changes in mass or charge of the parent ion (or both) are generally readily detected by all forms of tandem mass spectrometry. Charge changing, or charge permutation, reactions have a long history in mass spectrometry. However, with the advent of new ionization methods, such as electrospray ionization, and the expansion of tandem mass spectrometry instrumentation to include ion trapping instruments, the past decade has seen a major increase in the types of charge permutation reactions that can be studied. Most charge permutation reactions involve electrons or protons as the charge mediating agents. This report, therefore, provides an overview of charge permutation reactions involving protons or electrons. Particular emphasis is placed on processes that involve interactions of precursor ions with gaseous neutral species, electrons or oppositely charged ions. Charge permutation reactions involving electron gain/loss are described first according to a rough order of the energy required for the reaction beginning with the most endoergic reactions and ending with the most exoergic reactions. An analogous approach is then taken with charge permutation reactions involving proton gain/loss. Important charge permutation reactions discussed herein, among others, include those referred to as charge inversion, charge stripping, electron capture dissociation, collision-induced ionization and charge separation. These reaction types, and others described herein, are the subjects of active research and are also finding use in many current areas of application.
