For these monomers, both positions of attack were considered. In addition, reactivity of monomers with conjugated bonds toward //CH<sub>3</sub><sup>•</sup>// and //HOO<sup>•</sup>// were considered((butadiene (//Bu2ene//), hexatriene (//Hex3ene//), vinylnaphthalene (//ViNaph//), 2- and 4-vinylpyridines (//ViPy//), and 2- and 4-vinylpyrimidines (//ViPm//) )). The total number of calculated Transition States was somewhere around 100.
-All TSs had the same topology as shown [[.:ts|above]]. Among the possible conformations of products, those ones were chosen in which the new substituent (formerly the radical) was perpendicular to the original plane of the monomer. Table I presents the main geometric characteristics of TSs of β-attack (attack on the unsubstituted position of the //C=C// bond). One may judge from the table that TS geometries within a series remain practically constant. Comparison of r<sup>prod</sup>/r<sup>≠</sup> values shows that the //CH<sub>3</sub><sup>•</sup>// addition reaction has the earliest TS and the //HOO<sup>•</sup>// addition the latest, in due agreement with experimental facts.
