采用密度泛函理论方法，在B3LYP/6-31G*水平下全优化得到了该化合物的分子几何构型和电子结构；依据Onsager自恰反应场模型考察了其在氯仿、丙酮、二甲亚砜及水等溶剂中的溶剂化作用；基于气相优化结构进行了B3LYP/6-31G*振动分析，用0.9613校正后的主要红外光谱与实验符合得很好。

In this work, a full optimal calculation on the molecular geometry and electronic structure of C24H30O8 has been performed using density functional theory methods at B3LYP/6-31G(superscript *) level. The solvent effects of C24H30O8 have also been investigated based on Onsager self-consistent reaction field model in chloroform, acetone, DMSO and water. On the basis of optimized geometry in gas phase the vibration analysis is carried out and the IR principle peaks scaled by 0.9613 are in good agreement with experimental.
