We present measurements of H-1 and C-13 shielding for (2E)- and (2Z)-2-(acetyloamino)-N,N-dimethyl-3-phenylacrylamide isomers in solutions. Practically the same values of the shielding were obtained using internal and external referencing. For the interpretation, we explore DFT calculations of shieldings performed at the rovibrationally averaged geometries. The comparison of the experimental and theoretical results is verified both for the shielding and chemical shift. It appears that some inaccuracies in the calculations of the chemical shift can be reduced due to the error compensation while subtracting the reference shielding. As shown the measurement of magnetic shielding can be useful for molecular structural studies. (C) 2015 Elsevier B.V. All rights reserved.
