摘要
在293~393 K 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 700~750 cm-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。
Abstract
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 K to 393 K. The first key band frequencies and unreported the second key band frequencies were discovered in the band region from 700 to 750 cm-1. The temperature effect on bond intensity and ordered change were discussed also.
