The molecular structure of trans-cinnamaldehyde ((E)-3-phenyl-2-propenal) was determined by means of gas electron diffraction. The nozzle temperature was 165 °C. The results of B3LYP calculations with the 6-31G∗∗ basis set were used as Supporting information. It was found that this molecule has two stable conformers, s-cis and s-trans, which differ in the orientation of the CHO group. Their abundances at 165 °C were determined to be 25 ± 19% and 75%, for the s-cis and s-trans, respectively. This conformational composition is consistent with the prediction by the theoretical calculations. The determined structural parameters (rg and ∠α) of the more abundant conformer, s-trans, of trans-cinnamaldehyde are as follows:
