Data are part of a doctoral thesis that aimed developing a methodology to evaluate, by physical and chemical methods, the artificially carbonized wood of three specimens of the Araucariaceae family: Araucaria angustifolia, Araucaria bidwillii and Araucaria columnaris. The carbonization process of the wood fragments was carried out in a muffle. The burning temperatures of the carbonized in nature wood were from 200ºC to 600ºC, with a temperature ranging from 50ºC to 50ºC and with a heating rate of 25°C min-1. After the carbonization process, the spectra were acquired in the infrared spectrophotometer, in an interval between 1900 to 650 cm-1, with a resolution of 4 cm-1 and 64 scans.
