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.
2-(乙氧羰基甲氧基)-5-(芳偶氮)苯甲醛 1-4 和它们的肟 5-8 通过红外光谱、（1）H 和（13）C 核磁共振谱进行了合成和表征。通过理论预测了醛 1-4 和肟 5-8 的优势构象。从优化结构中得出了选定的几何参数和电荷。还使用 Gaussian-03 软件包计算了红外、（1）H 和（13）C NMR 数据，并与观察值进行了比较。还通过理论确定了（15）N 和（17）O 的化学位移。
