Low-frequency IR and NMR spectra for complexes of ICl with a series of substituted pyridines have been obtained in an attempt to study the factors which lead to a variation in donor ability when Me group substitution is made at different positions in the ring. The presence of even one α-Me group causes a significant decrease in the ν(N-I) (intermol.) band frequency and intensity (and in the kDI force constant) relative to those found in the absence of α-Me groups. On the other hand the ν(I-Cl) band intensity varies very little on going from one base to another while the NMR spectra show that electronic rearrangement within the base mols. can be correlated, at least to some extent, with their pKa values.
