Abstract:

In the present study we describe a simple synthesis of three mono-squaramides with amino acid amides residue. The structure of the compounds is elucidated by means of FTIR, Raman, NMR and elemental analysis. The structural and spectral analysis of the synthesized compounds are supported by theoretical analysis using DFT (B3LYP/6-311++G**) calculations. The simulated spectra satisfactorily coincide with the experimental ones.
