Wavenumbers tell us the number of wavelengths per unit distance and are given in units of cm-1. Light with shorter wavelengths and higher energy will have a larger wavenumber, while light that has longer wavelengths will have lower energy and wavenumbers. Mid-IR, near-IR, and far-IR ...

TheA1gphonon mode lying in the wavenumbers 511–515cm−1of the Raman spectra shifts toward the lower wavenumber, as the 48foxygenx-parameter decreases due to substitution at R-site by large cation from Y→Dy→Gd→Bi. To identify the IR activeF1umodes reappearing in the Raman spectra, ...

所以相应地削弱了C-O键级，导致了更弱的C-O键。这反映在IR谱中就是C-O振动峰的wavenumber变小了...
方法 以膝关节表面软骨及关节内游离体表面软骨为研究对象,通过FT-IR光谱成像的分析方法及主成分分析法,从分子水平辨别同处于一个关节腔微环境中两种软骨的差别。结果 两种软骨中作为填充物的蛋白多糖,没有明显的变化,二阶导数波数位置中1 514 cm-1所代表的胶原N-H弯曲振动(实验组为1 516 cm-1,对照组为1 514...
