Near-infrared spectra of selected organic compounds

3 Near-infrared spectra of selected organic compounds 

This text presents NIR spectra of a few common organic materials. In order to facilitate the assignment of bands, spectra of compounds belonging to homologous series are plotted together (Hitzeroth-Halfbrodt, 1988). A detailed discussion of near-infrared absorption due to C H vibrations has been presented by Goddu (1960). 

6 has already been introduced and discussed by Lippert and Mecke (1951)). The same result is obtained from the B versus n plot for the second overtone regions of C H stretches between 7500 and 9000 cm as shown by Fig. 6.2-2lb.
