Abstract

Abstract: An NMR method is presented for determining the rotational diffusion constants of the side-chains in polymer solutions and solids, that is, first, the correlation functions and spectral density functions of the rotation of the side-chains were derived, and then the rotational diffusion constants of these side-chains were determined with the aid of ¹³C spin relaxation data. Two applied examples are also discussed.

Key words: Rotational, Diffusion, Constant, Correlation function, ¹³C spin relaxation, Side-chain, Polymer
