Abstract

top
Raman spectra of acetamide CH3CONH2 in aqueous solution and in aqueous acid (HCl) solutions are given and discussed. The spectra make evident a gradual transformation of acetamide from a free to a protonated form. A structural hypothesis—oxonium ion—for the protonated form in aqueous acid solutions is advanced, extending the discussion to the Raman spectra of acetamide in aqueous (D2O) acid (DCl) solution, of acetamide hydrochloride (CH3CONH2)-HCl, crystalline and in aqueous acid solution, of acetic acid CH3COOH in aqueous acid (HCl) solution and of sodium acetamide CH3CONHNa. The hypotheses in the literature concerning the structure both of the protonated acetamide, cristalline and in aqueous solution, and of other amides are various and contrasting.
