Abstract The molecular structure of enflurane was studied by infrared (IR) spectrum methods (including transmission IR spectrum/T-IR spectrum, attenuated total reflection IR spectrum/ATR-IR spectrum and diffuse reflectance IR spectrum/DR-IR pectrum). It is found that the infrared absorption modes of enflurane mainly include the CH stretch vibration mode (νCH-enflurane), the CF2 stretch vibration mode (ν■) and CF stretch vibration mode (νCF-enflurane), the quality of enflurane T-IR spectrum is better than enflurane ATR-IR spectrum and enflurane DR-IR spectrum. This study expands the scope of application of IR spectroscopy in the study of the structure of important inhaled anesthetics (enflurane)
