Following a brief introduction to charge-transfer complexes, the far-infrared vacuum grating spectrometer used in this research is briefly discussed. The infrared spectra of the PyI2, PyIBr, PyIC1 and PyICN charge- transfer have been examined in a range of environments. The Raman spectra of PyIBr and PyIC1 have also been examined. In polar solvents the ionization 2PyIX ⇌ [Py2I]+ + IX2- takes place. The vibration spectra of the complexes are assigned. The infrared spectra of the complexes y-PicI2, y-PicIBr, y-PicICl and y-PicICN have been recorded in a range of environments. In polar solvents the first three complexes ionize 2y-PicIX ⇌ [y-Pic2I]+ + IX2- The vibrations of the complexes are assigned on the basis of C2v symmetry.
