【摘要】 采用红外光谱（包括：一维红外光谱和导数红外光谱）分别开展了地氟烷分子结构研究。结果发现，地氟烷分子红外吸收模式主要包括：CF₃官能团不对称伸缩振动模式(ν_{asCF3-地氟烷})、CF₃官能团对称伸缩振动模式(ν_{sCF3-地氟烷})、CF₂官能团不对称伸缩振动模式(ν_{asCF2-地氟烷})、CF₂官能团对称伸缩振动模式(ν_{sCF2-地氟烷})、C-F官能团伸缩振动模式(ν_{C-F-地氟烷})、C-O官能团伸缩振动模式(ν_{C-O-地氟烷})和C-F官能团伸缩振动和C-O官能团伸缩振动的混合模式(ν_{C-F-地氟烷}+ν_{C-O-地氟烷})。地氟烷分子结构的四阶导数红外光谱的谱图分辨能力要优于相应的一维、一阶导数、二阶导数和三阶导数红外光谱，并可以提供更加丰富的光谱信息。红外光谱可以快速开展地氟烷分子结构研究。更多还原

【Abstract】 The molecular structure of desflurane was studied using infrared spectroscopy, including one-dimensional infrared spectroscopy and derivative infrared spectroscopy. The results showed that the infrared absorption modes of desflurane molecules mainly include: CF₃ functional group asymmetric stretching vibration mode(ν_{asCF3-desflurane}), CF₃ functional group symmetric stretching vibration mode(νs_{CF3-desflurane}), CF₂ functional group asymmetric stretching vibration mode(ν_{asCF2-desflurane}), CF₂ functional group symmetric stretching vibration mode(ν_{sCF2-desflurane}), C-F functional group stretching vibration mode(ν_{C-F-desflurane}), C-O functional group stretching vibration mode(ν_{C-O-desflurane}), and a mixed mode of C-F functional group stretching vibration and C-O functional group stretching vibration(ν_{C-F-desflurane}+ ν_{C-O-desflurane}). The spectral resolution of the fourth derivative infrared spectrum of the molecular structure of desflurane is superior to the corresponding one-dimensional, first derivative, second derivative, and third derivative infrared spectra, and can provide richer spectral information. Infrared spectroscopy can quickly conduct research on the molecular structure of desflurane.更多还原
