Therefore, the centers are: (in cm - In Jaworska, et al., 2012, we find the following fingerprints for nicotinamide (solid state and solutions). In bold, the peaks which are corresponding to q-Gaussian centers given above, within +/-5 cm -1 (in italic, within +/-10 cm -1 ): According to Jaworska and coworkers, "the normal FT-Raman spectrum of the aqueous solution at low pH reveals the presence of two bands at 1030 and 1046 cm -1 , which are attributed to vibrations 1 and 12 of the pyridine ring, respectively. Mode 1 originates from the trigonal bend of the ring (breathing), while mode 12 is a combination of the ring C-C and C-N stretches". If we consider Figure in Jaworska et al., we can note that the intensity of the peak at 1030 cm -1 changes according to pH.
