Notes:
It was found that 1-substituted quaternary imidazolium compounds show some characteristic infrared (IR) activity. On quarternization of 1-substituted imidazoles strong absorption bands appeared at about 1150 and 1550 cm-1 in the IR spectra of these compounds. The band at 1150 cm-1 was assigned to the position 2 C-H bending mode and the 1550 cm-1 band was attributed to a ring vibration mode of the quaternary imidazolium compounds. The concentration of the quaternary imidazolium units in a polymer can be determined by measuring the intensity of the absorption bands at 1150 or 1550 cm-1 in relation to another suitable absorption band of the spectrum.
