Abstract
Effect of oxygen on ESR linewidth in polypyrrole has been studied to obtain information on the on-chain diffusion rate through the Houze-Nechtschein relaxation mechanism. Alternatively, the amplitude of angular dependent ESR linewidth AΔH in partially aligned polypyrrole is analyzed to obtain D∥ through the Elliott broadening, which makes it possible to separate Pauli contribution by subtracting Curie one from the observed. Finally, D∥ is found to be nearly proportional to T−n, n≈1/2, which can reproduce all the ESR linewidth data taken under He gas, air and oxygen atmospheres in the whole temperature-range.
