The experimental interpretation of FT-IR and Raman spectra of radezolid was conducted in combination with theoretical studies. Density functional theory (DFT) with the B3LYP hybrid functional was used for obtaining radezolid spectra. Full identification was carried out by COSY, 1H 13C} HSQC and 1H 13C} HMBC experiments. The experimental NMR chemical shifts and spin-spin coupling constants were compared
在提出的研究中,N-[((5S)-3-(2-fluoro-4'-[(1H-1,2,3-triazol-5-ylmethyl)amino] methyl} biphenyl-4-yl)合成了-2-氧代-1,3-氧杂唑烷-5-基]甲基}乙酰胺(radezolid),并用FT-IR,拉曼,ECD和NMR进行了表征。这项工作的目的是评估应用经典光谱方法(例如FT-IR,拉曼光谱,ECD和NMR光谱)进行雷迪唑烷的鉴定和光学纯度的可能性。结合理论研究进行了雷克唑利德的FT-IR和拉曼光谱的实验解释。使用具有B3LYP杂合功能的密度泛函理论(DFT)来获得雷克唑利德光谱。通过COSY,1H 13C} HSQC和1H 13C} HMBC实验进行完全鉴定。使用DFT方法和采用3-311 ++ G(d,p)基组和溶剂可极化连续体模型(PCM)的B3LYP功能,将实验NMR化学位移和自旋-自旋偶联常数
