Two extremal principles for the relaxation of the stressed conformation states can be formulated [1]. The first is – «The rate of PE decrease is maximal at every moment in time». The second is – «The rate of ED is minimal at a given rate of PE decreasing». In the asymptotic limit N>>1 there exists a very useful rule for molecular chain conformation dynamics in viscous medium: “Dihedral angles’ rotations occur in such a way that the average energy dissipation rate is uniformly distributed over all nodes of the molecular chain”. It demonstrates the collective effects for the rotations along the dihedral angles of the chain in a viscous medium, which arise from the action of friction forces only.
