We study detonation nanodiamond by RS. Samples were recieved in form of powder. Then we press this powder under high pressure 8GPa and T=1800C and got compact detonation nanodiamonds, that then were studied by RS. We saw the peak at ~ 4300 -4320 cm-1 in spectra of different samples. In literatura this peak is assigned to mode 2D+G in graphite. (We apparently see graphite phase in these sample). May this peak at ~ 4300-4320 cm-1 associate with bonding between H and C?
In prosess sythesic of nanodiamond powder is used composite of TNT-trinitrotuluen and hexogen
Thank you very much
Hello, Binh!
You must analyze relative intensities of all peaks. 2D+G is combinational mode. High intensity is less probable. H-C stretching modes are more probable. Usually they are more then 3000 cm-1.
Good luck!
Dear Binh
See these links attached it will help you.

How to divide luminiscence and Raman peaks in common case, Aurelio?
