hai....graphene and graphene oxide input files can be drawn manually using gaussview....it is not hard to build....or else, if u find its difficult, follow any publication in which authors might have given the coordinates in supporting. you can have them and continue your calculations....

moreover, graphene oxide structure is not yet known clearly....whoever work on it, they consider relative structure with oxygen functional groups....for your sake i have taken the inputs from publications and attached here....

All the best

Dear Lakmal Jayarathna

There is a program called “nanotube modeler” that you can download its free version from the internet. This program includes graphene input geometry in addition to nanotubes.

Thank for reply

When I was trying to export graphene sheet from "nanotube modeler"  but it was saying "Export function is disabled in unregistered version. What should I do to get it? This is not freeware I guess.

same thing happened in my case also.

"Export function is disabled in unregistered version"

R U got the input file?. If else just find with the following website

Dear Ch Venkata Surya Kumar

Thanks for your help.

Can anyone provide me Phosphorous doped Graphene input file for Gaussian 09? Which multiplicity should keep for P doped complex?

Thanks in advance
