We present Raman spectroscopy of exfoliated graphene layers and chemically- modified exfoliated graphene samples. We show that the home-built Raman spectroscope can be used to differentiate graphene films from graphite and chemically-modified graphene films from unmodified ones. Structural differences of chemically-modified graphene samples can be inferred from the differences in the spectra and can be related to the modification the samples have undergone.
