Abstract

The processes leading to the fragment ions formed from alkylthiophene molecule ions by benzylic cleavage without and with transfer of one hydrogen from the side‐chain to the ring and the influence of additional methyl groups on the relative importance of these two fragmentation reactions were investigated.

The dynamics of polymer chains, such as +-A-BR-BR jX, are investigated by means of the equivalent linear polymer chains, $-A-B'-B'+-X, with the probability p of movement of bead B'. It is found that the relaxation times of the equivalent linear polymer chains obey the relation T,(p) = T,.p -Et, wher
