According to Johnson's Rule and IR spectra, their possible structures are suggested. The bonding parameters of those complexes are calculated by ESR parameters. And the crystal field parameters are calculated by using electronic spectral data. It can be seen that the vanadyl complexes in the solution are ionic complexes and that the α〓 values of those complexes decrease following the increasing of the N donor replacing the O donor of water on the equatorial plane in those complexes. This means that the covalent bonding between vanadium and ligand increases as Ser, Phen or Bipy replace water ligands. The results show the competitive coordinate law that the coordination reactivity of Phen and Bipy is much stronger than that of Ser. The simulation program of ESR is compiled by the theory of ESR in the present work.

测定了VO-丝氨酸二元体系、VO-丝氨酸-邻菲咯啉三元体系和VO-丝氨酸联吡啶三元体系在不同酸度下（pH=1.0～14.0）的乙二醇／水（V／V=1：1）溶液低温ESR谱，发现不同pH下，溶液中具有不同组成的配合物，根据不同pH下ESR谱的变化，利用Johnson的加合规则并结合红外光谱，推测了它们在溶液中的可能结构；利用波谱参数计算了配合物键参数；利用电子光谱数据计算了配合物的晶体场参数，讨沦了它们的成配特性，结果表明：VO配合物属离子型配合物，随取代水分子的配体（Ser、Phen或Bipy）数目增加，键参数减小，配合物共价性增强，同时得出这些体系中，生物配体竞争配位规律：Phen和Bipy与VO的配位能力比Ser强。
