Complementary ions peak intensities

TABLE 5.1. IE of the Fragments and Peak Intensities of the Complementary Ions... 

The distonic species 33 (X = F, Cl and Br) were produced in low yields from the corresponding 3-halopropanols XCH2CH2CH2OH via El-induced CH20 loss122. The structural assignments were made on the basis of their CID spectra, which are characterized by intense peaks due to the complementary ions C2H4+ and HX+ . 

The second reactions represented in Schemes 5.15 and 5.16 deal with the same initial ion and the same products. The essence consists in the question, which of two complementary particles retains the charge To estimate the intensity of the alternative peaks one should use Stevenson s mle (Section 5.4.1.2). To propose a mechanism of the process (in terms of the described concept) it is necessary to take into account that stabilization of the charge is more important than stabilization of the radical (see above). As the reactions initiated by the charge involve charge migration, they are usually less favorable in comparison with the alternative reactions initiated by the radical center.
