检测了地塞米松磷酸钠和倍他米松磷酸钠两种差向异构体的红外光谱(FTIR), 固体和饱和溶液的常规拉曼光谱(NRS)及以银胶为基底的表面增强拉曼光谱(SERS)。通过红外和拉曼光谱的结合，对其各基团的振动模式进行解析，并对峰进行归属和比较。结果表明：两种物质的主要区别是地塞米松磷酸钠的CH3非对称伸缩振动和对称面内变形振动的拉曼位移较大;依据SERS作用机理和规律，推测两种物质在银胶上主要是通过P—...
本文首次利用近红外傅立叶变换拉曼(NIR FT-Raman)和傅立叶变换红外(FT-IR)光谱法无损快速鉴别了八角茴香和伪品莽草、红茴香。结果表明:八角茴香和伪品莽草、红茴香在拉曼和红外谱图中均有各自的特征峰,可容易地将它们区别开来。该方法具有快速、准确、操作简单、不需对样品进行提取分离,可直接进行测定等特点。
摘要在热天平上采用慢速升温制备了褐煤、高挥发分烟煤和低挥发分烟煤的半焦。采用FT-Raman光谱对半焦进行了分析。半焦800 cm-1至1 800 cm-1的Raman光谱可分解为10个谱带，以表征高度无序炭材料中的典型结构。光谱和谱带的强度比都可用来描述半焦的结构特征。在600 ℃低温热解时，三种煤半焦的结构差异明显。随热解温度升至800 ℃或900 ℃，这种差别消失。褐煤中可交换的钠离子影响热...
FTIR and FT-Raman Spectral Investigations on 4-Aminoquinaldine and 5-Aminoquinoline
FTIR FT-Raman normal coordinate analysis (NCA) potential energy distribution (PED) and simple general valance force field (SGVFF)

The FTIR spectra of 4-aminoquinaldine and 5-aminoquinoline were recorded in solid phase on a Bruker IFS 66V spectrometer in the region 4000--400 cm-1. The FT-Raman spectra of these compounds were also...
FT-IR and FT-Raman Studies on 3-Aminophthalhydrazide and N-Aminophthalimide
3-aminophthalhydrazide N-aminophthalimide FTIR FT-Raman and normal coordinate analysis
2010/4/22
The FT-infrared (400-4000 cm-1 ) and FT-Raman (100-3500 cm-1 ) spectra of N-aminophthalimide and 3-aminophthalhydrazide were recorded. The observed frequencies were assigned to various modes of vibrat...
