Abstract

The structures of bilirubin in solid-state, in HCCl3 and DMSO solution are investigated by FTIR spectroscopy. The results indicate that bilirubin have very different structures in solid-state and in solutions. The results also demonstrate that the structures vary in different solvents. There are six H-bonds in bilirubin molecule in solid-state, four in bilirubin molecule in HCCl3 solution and one in bilirubin molecule in DMSO solution.

摘要

通过傅里叶变换红外光谱（FTIR）研究了胆红素在固态、三氯甲烷（HCCl3）和二甲基亚砜（DMSO）溶液中的结构。结果表明，胆红素在固态和溶液中的结构差异很大。结果还表明，其结构在不同溶剂中有所不同。固态胆红素分子中有六个氢键，三氯甲烷溶液中的胆红素分子中有四个氢键，二甲基亚砜溶液中的胆红素分子中有一个氢键。
