Fourier transform infrared (FT-IR) and Raman (FT-Raman) spectra of 5-aminoindole has been recorded and analysed. The FT-IR spectrum of the compound was recorded in a BrukerIFS 66 V spectrometer in the range 4000-400 cm(-1) and the FT-Raman spectrum was also recorded in the same instrument in the region 3500-100 cm(-1). Observed frequencies for normal modes are compared with those calculated form normal co-ordinate analysis. The shift in the frequencies of the fundamental modes with the substituent amino group and the mixing of different normal modes are discussed with the help of potential energy distribution (PED) calculated through normal co-ordinate analysis.
已记录并分析了5-氨基吲哚的傅里叶变换红外（FT-IR）光谱和拉曼（FT-拉曼）光谱。该化合物的FT-IR光谱在Bruker IFS 66 V光谱仪上于4000 - 400 cm⁻¹范围内记录，FT-拉曼光谱也在同一仪器上于3500 - 100 cm⁻¹区域记录。将观察到的正常模式频率与通过正常坐标分析计算得到的频率进行比较。借助通过正常坐标分析计算的势能分布（PED），讨论了带有取代氨基的基本模式频率的变化以及不同正常模式的混合情况。
