Looking for a direct quantification method that evaluates the difference primarily reflected due to the carbon coordination. If any relevant literature is available please share. Thanks in advance.
Yes, I knew the Id/Ig from IR gives some idea and I do use this method. As you know, this ratio gives an overall picture due to several reasons including substitutions by any hetero species on the basal plane. However, our interest is to see change in C atom coordination due to difference in its own bonding (with in C atoms). For instance switching from six membered carbon ring to 5 membered carbon ring when the graphene is bending (losing its basal planarity). I understand that my question should have been more specific. I am sorry and I hope it is more clear now. Thanks.
If you have a possibility to use Scanning Tunneling Microscopy analysis, probably, you can obtain information regarding the quantification of relative exisitance.
