These metal complexes in which ions were mosaiced into big? system of conjugated ring structrue were demonstrated by π→π transition energy, transition probability and Nlt shift of binding energy.
由π→π跃迁能、跃迁几率及N(1S)和金属M(2p3/2)结合能的位移证明,这些化合物是金属镶嵌在大π体系共轭环中而成的金属配合物。
Result: The purified tannin product obtained from Galla Chinensis contains NLT 98% of tannic acid and less than 0. 2% of gallic acid, and has stable HPLC characteristic spectrum.
结果:五倍子鞣酸精制品含量≥98%,没食子酸含量<0.2%,具稳定的HPLC特征图谱。
