本文采用元素分析、紫外吸收光谱、红外吸收光谱、质谱和核磁共振（NMR）波谱（包含¹H NMR、¹³C NMR、DEPT、¹H-¹H COSY、¹H-¹³C HSQC和¹H-¹³C HMBC）等方法对德拉沙星葡甲胺进行了结构分析，确证了德拉沙星葡甲胺的结构，分析了其IR谱图特征吸收峰对应的基团，对其¹H和¹³C NMR信号进行了完整归属.并通过差示扫描量热法、热重分析及粉末X-射线衍射分析对德拉沙星葡甲胺的晶型进行了初步研究.

Spectroscopic Studies of Delafloxacin Meglumine

The structure of delafloxacin meglumine was analyzed by infrared absorption (IR), ultraviolet absorption (UV), nuclear magnetic resonance (¹H NMR, ¹³C NMR, DEPT, ¹H-¹H COSY, ¹H-¹³C HSQC and ¹H-¹³C HMBC) spectroscopy, mass spectrometry and elemental analysis. The characteristic absorption peaks in the IR spectra were discussed. The ¹H and ¹³C NMR signals of delafloxacin meglumine were assigned, and the two-dimensional signals were used to elucidate its structure. The crystal structure of delafloxacin meglumine was studied by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and powder X-ray diffraction (PXRD).
