VO(Ⅱ)-苯甲酰异羟肟酸配合物的ESR波谱研究
Studies on the ESR Spectra of Vanadyl Benzohydroxamate
【摘要】 本文研究了VO(Ⅱ)-苯甲酰异羟肟酸配合物在一系列溶剂中室温和低温下的ESR波谱,讨论了不同溶剂对常温下各向同性波谱的线宽和超精细分裂常数的影响。通过测定不同溶剂中的低温各向异性ESR波谱得到的g_(11),g_⊥,A_(11),A_⊥等波谱参数,结合电子光谱测定的d-d跃迁数据,计算出α ̄2,K,β ̄2,γ ̄2等键参数,并讨论了溶剂对配合物电子结构的影响。
【Abstract】 The ESR spectra of vandyl Benzoxamate have been studied in a number of organic sol-vents and frozen glasses.The spectra have been analyzed in detail.The solvent effects on theESR spectra have been disscussed,From the anisotropic ESR spectral parameters obtained at-150℃,together with the d-d transition energies from electronic spectra,the molecular bondparameters α ̄2,K,β ̄2,γ ̄2 have been calculated , effects of solvent on electronic structure ofVO(BHA)2 also have been discussed.
