  We carried out a joint analysis of the INS, DRIFT, and XPS spectra of a set
of sp2 amorphous carbons of the highest carbonization rank representing natural
substances (shungite carbon, anthraxolite, and anthracite), technical graphenes
(laboratory reduced graphene oxides), and industrial products (carbon blacks).
It was determined, that the DRIFT spectra of the studied substances consist of
two components determined by hydrogen and oxygen compositions in the
circumference of graphene molecules, which represent the basic structural units
of amorphic compounds. Methine groups typify the hydrogen component of natural
amorphics while hydroxymethyls and methyls do the same job for the studied
technical graphenes and hydroxyfurans for carbon blacks. A particular
specificity of the methine-based hydrogen compositions to enhance electrooptic
characteristics of the DRIFT spectrum of carbon atoms has been established. A
comparable analysis of DRIFT and XPS spectra has allowed a reliable
personification of the oxygen functional groups compositions of the studied
amorphics resulting in a set of dependable molecular models of their basic
structural units.
