FTIR and FT-Raman spectral investigations on 4-aminoquinaldine and 5-aminoquinoline

The FTIR spectra of 4-aminoquinaldine mid 5-aminoquinoline were recorded in solid phase oil a Bruker IFS 66V spectrometer in the region 4000-400 cm(-1). The FT-Raman spectra of these compounds were also recorded in the same instrument with a FRA 106 Raman module. The molecules under investigation are considered to have a CS point group by assuming, the -NH2 mid -CH3 groups as point masses. All the vibritions are both IR mid Raman active. The simple general valance force field (SGVFF) is adopted for both inplane and out of plane vibrations. All the frequencies are assigned in terms of fundamentals, overtones and combinations. The general agreements between the observed and calculated frequencies are satisfactory.
