Brownson, G. W. published the artcileFar-infrared intensity and normal coordinate studies on pyridine-halogen complexes, SDS of cas: 6443-90-9, the publication is Journal of Molecular Structure (1971), 10(1), 147-53, database is CAplus.
Absolute integrated intensity data were determined for the 2 low frequency bands due to ν(D-I) and ν(I-X) in pyridine-IX (X=I, Cl, Br) complexes. Along with the normal coordinates, calculated by using a linear triat. model, these data were used to calculate dipole derivatives * vecμ/* j values. Pyridine-d5-IBr spectra were used to estimate possible values of the interaction force constant k13. The dipole moment change * vecμ/* D-I calculated for the pyridine-I2 complex by using a simple model is considerably lower than that observed, implying that charge-transfer effects contribute significantly to the band intensities.
