Dielectric relaxation in NH---N bond complexes

Dielectric relaxation measurements on NH---N bonded complexes of pyrrole and indole with pyridine and quinoline molecules respectively have been undertaken at a 9.8 GHz frequency over a range of temperatures 293 –323 K by use of the method of Gopala Krishna[1], Higasi[2] and Higasi, Koga and Nakamura [3]. The observed results indicate the presence of NH---N bonded complexes in the above temperature range under the microwave field. The dipole moments associated with the complexes and thermodynamical parameters have also been determined, and the results obtained exhibit formation of NH---N bond, which behave as a single unit under the applied field.
