I don't have, but for sure this is something rather uncommon, as there is just nothing to see !! FT-IR spectroscopy allows to evidence surface functions, which are almost absent in pure graphite. Only C-H bonds exist at the carbon edges, but in negligible amounts compared to the amounts of C-C/C=C bonds in the bulk. So if your spectrum shows well-identified bands, you can be sure that it is definitely not graphite but a disordered (and probably porous) carbon full of surface functions. In the latter case only, FT-IR is a relevant method. For other cases, Ramal spectroscopy is far better and useful.
