In this paper, we report first, the synthesis of three α-aminophosphonic acids from Meta-aminophenol, Ortho-aminophenol and Para-aminophenol. Then, we present a detailed DFT study based on B3LYP/6-31G (d, p) of geometrical structures and electronic properties of these compounds. The vibrational frequencies determined experimentally were compared with DFT gradient calculations which were obtained theoretically
