Key Points

• The aim is to clarify inaccuracies in the interpretation of the infrared spectrum of diethylmethylammonium triflate.
• Review of a recent article on DEMA TfO's infrared spectrum.
• Analysis of reported spectral data.
• Identified errors in the assignment of infrared peaks for DEMA TfO.
• Highlighted the implications of inaccurate spectral analysis on understanding ionic liquids.
