I can calculate ID/IG and I2D/IG ratio and number of layers from intensity of peaks.
Is there anymore information can be derived from the spectra?
What could be the potential reason for the widened 2D peak?
What are the origins of two short peaks around ~2400 and 2900 cm-1?
Dear Siam Uddin
Raman spectra is helpful in identification and understanding of nature of functional groups (such as epoxy, carbonyl, carboxyl, hydroxy etc.) on the surface of graphene sheets.
please go through these articles for better understanding:
