Infrared Absorption Spectra of Molecular Complexes of Pyridine. Part III : Molecular Complexes with Iodine and Iodine Halides
When iodine or iodine halides were dissolved in pyridine, new bands were observed at 624-627, 1012-1007, 1213, 1246, and 1454 cm^<-1>, which were assigned as the shifted bands of ν_<6a>, ν_1, ν_3, 2ν_<6a> andν_<19b> respectively of pyridine. The rest of the absorption bands of pyridine solutions was found as the same band location and intensity as those of the pure pyridine spectrum. Solid spectra of the complexes were assigned by an analogy with the solution spectra. The extent of shifts of 624-627 cm^<-1> and 1007-1012 cm^<-1> bands were correlated to electronegativities of interhalogen compounds, that is, iodine chloride made a band shift markedly from the pure pyridine spectrum.
