In this work, the structural and vibrational properties of 1-5-(difluoromethyl-1H-pyrrol-2-yl-) ethanone (DFPE) were studied by using the hybrid B3LYP/6-31G* method. The properties were analyzed and compared with those obtained for 1-(1H-pyrrol-2-yl) ethanone (PE) and 1-(5-(trifluoromethyl)-1H-pyrrol-2-yl) ethanone (TFPE). The theoretical 1H-NMR, 13C-NMR and 19F-NMR chemical shifts for DFPE were predicted by using the B3LYP/6-311++G** approach with the GIAO and CGST methods showing the three spectra good concordances with the corresponding experimental ones. A complete assignment of the vibrational spectra was presented.
