We reported the synthesis of (2E)-33-methoxy-4-1(3-methylbut-2-en-1-yl)oxy]phenyl)-1-(3,4,5-trimethoxyphenyl)prop-2-en-1-one. The molecular structure and spectroscopic properties of this compound were calculated using the density functional theory (OFT) method with the B3LYP hybrid functional in combination with Pople type 6-311++G(d,p) basis set. The geometry analysis shows that the calculated bond angles and bond distances have a satisfactory relation compared with experimental values. The NMR studies were realized using the CIAO Method, a satisfactory linear correlation was observed for H-1 with r = 0.993 and C-13 with r = 0.988, finding the highest value for H-1 NMR spectrum. The analysis of IR spectra shows a good correlation with the theoretical spectrum. The results show that the DFT-B3LYP/6-311++G(d,p) can describe with a good correlation the spectroscopic properties of the chalcone analyzed. (C) 2012 Elsevier B.V. All rights reserved.
