amine ftir spectrum

The C-C ring stretching vibrations occur in the region 1652-1579 cm-1 in FTIR spectra and 1608-1581 cm-1 in FT-Raman spectra. FTIR spectroscopy works by shining infrared radiation on a sample and seeing which wavelengths of radiation in the infrared region of the spectrum are absorbed by the sample.

Note the shoulder band which is an overtone of the NH bending vibration. In all figures we present a partial 1800800 cm 1 FTIR spectrum collected during the CO 2 bubbling. This structure is also available as a 2d Mol file or as a computed 3d SD file The 3d structure may be viewed using Java or Javascript.

Except where noted spectra from this collection were measured on dispersive instruments often in carefully selected solvents and hence may differ in detail from measurements on FTIR instruments or in other chemical environments. The value for absorption is usually in cm -1. Figure 51 represents the FTIR region between 1490 to 1690 cm-1 that contains the amine and carboxamide bands.
