“…The data were obtained by collecting 64 k data points at the acquisition rate of 5333 kHz and were subjected to Hanning apodization followed by one zero-fill prior to Fourier transformation. Each reaction spectrum was subjected to background correction by using a previously described procedure [34].…”

“…CS 3 •ϩ ions were the reactive intermediates in this process [28,29]. The reactivity of acetonitrile N-sulfide ions towards pyridine is found quite different in this last case, see Table 1.…”

“…Whereas the very efficient S •ϩ transfer reaction probably involves the intermediacy of several ion-molecule complexes, the thiazolopyridinium ion formation is likely to be initiated by an electrophilic attack of the R-C §N ϩ -S Positively-charged distonic ions have been the focus of intense gas-phase and computational research since the discovery in 1984 that these ions are surprisingly stable, and sometimes even more stable than their conventional counterparts [1,2]. It was also demonstrated that many conventional radical cations can isomerize into their distonic isomeric structures, spontaneously [3] or via the intermediacy of ion-molecule reactions [4]. Numerous other distonic ions have been purposely produced through complex MS n procedures to address several fundamental chemical questions [5].…”

“…The uncertainty in the pressure readings of the ion gauge used in this study was corrected by measuring the rate of the highly exothermic electron-transfer reaction between argon radical cation and the neutral reagent (TMB). It can be assumed that this reaction proceeds at the collision rate (k collision ), which can be calculated [39][40][41][42]. Any reaction occurring at collision rate has 100% efficiency.…”

“…The theoretical collision rate constants (k coll ) were obtained by using a parameterized trajectory theory [39][40][41][42]. The efficiency of each reaction (the fraction of collisions that leads to reaction) is given by k exp /k coll .…”
