The infrared absorption spectra of the normal 2,4-dienaldehydes, from pentadienal through dodecadienal, were measured in the liquid state over the spectral range from 400 to 4000 cm<sup>−1</sup>. The compounds were prepared by conventional methods and purified by gas-liquid chromatographic procedures immediately before spectrophotometry. Two strong bands near 1685 and 1643 cm<sup>−1</sup>, four strong bands in the 980-1180 cm<sup>−1</sup> region, and a doublet in the aldehyde C-H stretching region are characteristic of the <i>n-2 trans, 4 trans</i> dienal structure.
