摘要
在293-393K温度范围内,分别采用一维红外光谱、二阶导数红外光谱和二维红外光谱测定硬脂酸亚甲基面内摇摆振动（ρCH2）。实验发现：在700-750cm^-1范围内,硬脂酸ρCHα存在＂第一特征谱带＂和未见文献报道的＂第二特征谱带＂。并进一步研究了温度对于硬脂酸ρCH2红外吸收强度及变化顺序的影响。
The methylene rocking vibration（ρCH2）of one-dimensional infrared spectroscopy,second derivative infrared spectroscopy and two-dimensional infrared spectroscopy were measured in the temperature range from 293 Kto 393K.The first key band frequencies and unreported the second key band frequencies were discovered in the band region from 700to750cm^-1.The temperature effect on bond intensity and ordered change were discussed also.
