Confinement-induced mode consequences

In the experiment, the normal mode is related to the fluctuations of the end-to-end vector of free (nonimmobilized) chains, while the novel relaxation process was assigned to the fluctuations of the end-to-end distance of terminal subchains (hence, the confinement-induced mode is by its nature also a normal mode, not of the whole chain but of the terminal subchains only). The dynamics of these two relaxation processes is related to the corresponding end-to-end distances, consequently, their distribution, in dependence on thickness and molecular weight, is simulated in our study.
