The nature of hydrogen bonding within intermolecular complexes of carboxylic acids and 1- methylimidazole (1-MeIm), 1-n-butylimidazole (1-BuIm), and 1-tert-butylimidazole (1-t-BuIm) in chloroform was characterized by Fourier transform infrared spectroscopy. Earlier spectroscopic studies indicated that carboxylic acid–1-MeIm complexes are of three types:(I) neutral complexes with the weaker acids (pKa 2.2) in which the antisymmetric carbonyl ...
