Layered Inclusion Compounds Containing Aniline and Polyaniline Studied by NQR and IR Spectroscopy

Temperature dependence of the 127I NQR frequencies in the intercalates of PbI2 with aniline were measured. Unusual temperature coefficients of frequency and the electric field gradient asymmetry parameters for these compounds were discussed, taking into account the structure peculiarities and the amplitude of iodine oscillations.
