In recent years, green alternative solvents named Deep Eutectic Solvents (DESs) attracted the interest of researchers in the field of green chemistry due to their significant properties. The investigation of functional groups forming DESs helps to deeply understand their nanostructures. In this article, Fourier transform infrared spectroscopy (FT-IR) analysis was conducted for ammonium based DESs to highlight their chemical structure. The functional groups of the prepared DESs were quite similar to their hydrogen bond donors (HBDs) with new peak represents the ammonium identity of the DESs. The findings of this study were compared with previous research for phosphonium based DESs. It was reported that phosphonium based DES forms more peaks compared to ammonium based DES. This investigation is considered as a novel work that has been done for the first time on functional groups of choline chloride (CHCl) based DESs except for DES1 (triethylene glycol (TEG):CHCl) which was investigated previously.
