The solid state C-13 NMR and infrared spectra of Beypazan lignite were deconvoluted by the least squares curve fitting techniques to resolve the overlapping bands in the 0-220 ppm region of the C-13 NMR spectra and in the 4000-2700 cm-1, 1860-900 cm-1 and 900-400 cm-1 regions of the infrared spectrum to gain information about the structure of the lignite. Measurement of integral absorptivities of some of the functional groups present in the infrared spectra was attempted. Measured values of integral absorptivities are in good agreement with those reported previously.
