Abstract
In this work, the samples of α-fractions isolated from the pitches of different grades (B, B1, V) obtained from an industrial sample of coal tar are studied. The main numerical characteristics obtained from the Raman spectra of the isolated α-fractions are calculated and analysed. A direct relationship is established between the content of defects in graphite-like crystallites and the pitch softening temperature.
