How do different parameters influence the Raman spectrum of defect assisted bands in terms of - position, FWHM and intensity of disordered graphene?

We know that, when lattice periodicity is broken by a defect, the defect bands evolve. Also we know that the parameters such as point defects (vacancies, interstitial), sp3 related point defects...
