摘　　要：采用中红外光谱及变温中红外光谱技术对氧化锌的分子结构和热变性进行研究,为氧化锌的应用研究提供重要的科学依据。试验发现:氧化锌表面含有碳酸锌。碳酸锌的主要官能团CO_(3)的红外吸收模式主要有不对称伸缩振动模式、对称伸缩振动模式、面外弯曲振动模式和面内弯曲振动模式四种;在303~573 K温度范围内,碳酸锌CO_(3)对应的吸收强度及频率都有明显的改变。The molecular structure and thermal denaturation of zinc oxide are studied by mid⁃infrared spectroscopy and temperature⁃variable mid⁃infrared spectroscopy,which provides an important scientific basis for the application research of zinc oxide.The test found that the surface of zinc oxide contains zinc carbonate.The infrared absorption modes of CO_(3),the main functional group of zinc carbonate,mainly include asymmetric stretching vibration mode,symmetric stretching vibration mode,out⁃of⁃plane bending vibration mode and in⁃plane bending vibration mode;in the temperature range of 303~573 K,zinc carbonate CO_(3) corresponds to absorption intensity and frequency have obvious changes.
