  A still amazing identity of the D-G doublet Raman spectra of parental and
reduced graphene oxides is considered from the digital twins viewpoint. About
thirty DTs, presenting different aspects of the GO structure and properties,
were virtually synthesized using atomic spin-density algorithm, which allowed
reliably displaying reasons for this extraordinary spectral feature. In both
cases, it was established that the D-G doublets owe their origin to the sp3-sp2
C-C stretchings, respectively. This outwardly similar community of the doublets
origin of GO and rGO is thoroughly analyzed to reveal different grounds of the
feature in the two cases. Multilayer packing of individual rGO molecules in
stacks, in the first case, and spin-influenced prohibition of the 100%
oxidative reaction, the termination of which is accompanied with a particular
set of highly ordered by length sp3- and sp2 C-C bonds, protecting the carbon
carcass from destruction caused by the stress induced sp2-to-sp3
transformation, in the second, are the main reasons. The DT concept has been
realized on the basis of virtual vibrational spectrometer HF Spectrodyn.
