Differential anomalous scattering studies of amorphous hbr-doped polyaniline

The local molecular structure of amorphous HBr-doped polyaniline has been probed using conventional and differential anomalous scattering in conjunction with a single chain modelling analysis. Initial results identify a probable Br-ion site along the polymer chain approximately 3.3إ above (or below) the average polyaniline molecular plane and situated, on average, 3.7إ from the closest neighboring amine nitrogen.
