Study of the Halogen Bonding between Pyridine and Perfluoroalkyl Iodide in Solution Phase Using the Combination of FTIR and ¹⁹F NMR

Figure 4

Change in the chemical shift of ¹⁹F in the perfluoroalkyl iodides upon dilution with hexane (from Figure 4 to Figure 8, the upper panel is for 1-C₃F₇I, the lower panel is for iso-C₃F₇I, Δ𝛿=𝛿_solution−𝛿_pure1-C3F7I for 1-C₃F₇I, and for iso-C₃F₇I, Δ𝛿=𝛿_solution−𝛿_{pureiso-C3F7I}).
