Spectroscopic Characterization of a Sulfonated Product Containing Amide and Methylene Groups

The -SO32- group exhibits clearly distinguishable symmetrical and asymmetrical absorption peaks at 1129 cm-1 and 1044 cm-1, respectively. This suggests that the product comprises specific groups, namely amide groups and sulfonic acid groups. The vibrational mode of the elongated methylene group demonstrates a distinctive skewing effect at 780 cm-1. Considering the analysis of static light scattering results, the desired product has been successfully synthesized.
