2‐(Ethoxycarbonylmethoxy)‐5‐(arylazo)benzaldehydes 1–4 and their oximes 5–8 were synthesized and characterized by IR, 1 H and 13 C NMR spectroscopy. The favoured conformations of aldehydes 1–4 and oximes 5–8 were predicted theoretically. Selected geometrical parameters and charges were derived from optimized structures. IR, 1 H and 13 C NMR data were also computed using Gaussian‐03 package and compared with the observed values. 15 N and 17 O chemical shifts were also determined theoretically.
