3500cm-1处的吸收峰为-OH的伸缩振动；2970cm-1与2935cm-1处的吸收峰为-CH3与-CH2的伸缩振动；1738cm-1处的吸收峰为C=O的伸缩振动；1684cm-1处的吸收峰为C=C的伸缩振动；1601cm-1处的吸收峰为C=C-C=C的伸缩振动；1456cm-1处的吸收峰为-CH2的弯曲振动；1371cm-1处的吸收峰为-CH3的弯曲振动；1240cm-1与1167cm-1处的吸收峰为酯基C-O-C的伸缩振动；1055cm-1处的吸收峰为C-O-C的伸缩振动。上述数据与前人报道的泰万菌素数据基本一致。
The absorption peak at 3500cm-1 is ascribed to the stretching vibration of -OH;
the absorption peaks at 2970cm-1 and 2935cm-1 are due to the stretching vibration of -CH3 and -CH2, respectively;
the absorption peak at 1738cm-1 is ascribed to the stretching vibration of C=O;
the absorption peak at 1684cm-1 is ascribed to the stretching vibration of C=C;
the absorption peak at 1601cm-1 is ascribed to the stretching vibration of C=C-C=C;
the absorption peak at 1456cm-1 is ascribed to the flexural vibration of -CH2;
the absorption peak at 1371cm-1 is ascribed to the flexural vibration of -CH3;
the absorption peaks at 1240cm-1 and 1167cm-1 are due to the stretching vibration of C-O-C of ester group;
the absorption peak at 1055cm-1 is ascribed to the stretching vibration of C-O-C.
All these data are approximately consistent with the data on Aivlosin Tartrate reported by former researchers. |
