Polyaniline samples of different molecular weights were prepared using aniline enriched with ~ SN. Molecular weights were determined by gel permeation chromatography (g.p.c.). 15N n.m.r, spectroscopy confirmed that both samples were in the emeraldine oxidation state, and end group analysis techniques were used to compare molecular weights derived from g.p.c, with those from the n.m.r, data. In addition, the ~ 5N solid state n.m.r, spectra of emeraldine hydrochloride and a solvent-cast, oriented film of emeraldine base are presented
