Daer Dr Hessein,
a=2.46 is lattice parameters of pristine graphene.
I think Mr Maniraj question isn't clear.
Do you want about computational value?
I think hkl values are different from cell parameters.
cell parameters of graphene oxide are dependent on O atom concentration.
The c-value will be depended on the concentration of functional groups and on the intercalation of the groups between the GO layers. Therefore, you should measure the experimantal sample. but the theory could be very different.
Usually C is determined as does not exist any interaction between two adjacent layer.
I use c=15 or 20 angestrom.
Thank you Ms Sadighian,
These are XRD spectrum information. Graphene and Graphene Oxide don't have Bravais lattice.
Also you can find cell parameters of these compounds by calculating C-C bond length in every one.
Very thanks all for ur prompt reply to my question....sorry for delayed reply...first of all i will tell clearly my question now
Actually i preapared GO (graphene oxide) by improved method (ACS Nano,2010).i have taken XRD for that GO with wide angle (5-100).Many people reported that one peak around 10-12 degree (001 plane) for GO.But i got four peaks including that 10 degree..(details of my peak, 9.7, 42,83 and 97). that y i have confused lot to predict the XRD pattern of GO. So please let me know how can give explanation for higher degree pattern of GO.
I tried lot to find out cell parameter value (a and c) , because GO is hexagonal stucture.
I think that i cant take computational cell parametes of GO. It s varying much as compared to experimental reports...
So suggest me to understand the XRD pattern of GO ......
just go through this link.. you may get it

please may i know cell parameter values of graphene oxide and RGO for computational input...... please
