Table 5: FTIR-ATR bands identification and characterization of the pigments from the extracts. All the pigment extracts showed a \"noise\", which was associated with the humidity present in the air and carbon dioxide. This disturbance was visible in greater predominance between 400 and 700 cm\({}^{-1}\) (chemical bounds related to C-O bonds of various compounds) and 1800 and 2300 cm\({}^{-1}\) (carbon dioxide area). Pigments A and B present the spectra peaks substantially in the same areas. However, analyzing the main peaks present in the FTIR-ATR spectra and the respective connections allows us to reach the conclusion that it can be either a chlorophyll or a carotenoid.
