摘要: This article demonstrates how main-chain degradation can serve to study motions of macromolecules and obtain information on segment-segment interactions the basis light scattering (LS) measurements in conjunction with flash photolysis or pulse radiolysis. The LS detection method is a powerful tool kinetics mechanisms reactions solution. Moreover, it be used dynamic phenomena polymer solutions. reports concerning dynamics synthetic biological polymers. Preference given here problems lifetime polymer-polymer dilute for these studies are fast chemical leading scission. In certain cases rate reaction much faster than consecutive processes involving motion fragments finally separation fragments. intensity change reflects fragment motion. Typical results applying contact pairs formed by interacting repeating units some linear polymers salt bridges between strands biopolymers reported.
