The profiles of the 2D bands are very similar having only one component, contrary to the four found for commensurate Bernal bilayers. These results agree with recent theoretical calculations and point to the similarity of the electronic structures of single layer graphene and misoriented bilayer graphene. Another new aspect is that the dependance of the 2D frequency on the laser excitation energy is different in these two latter systems. %G English %2 https://hal.science/hal-00276997/document %2 https://hal.science/hal-00276997/file/graphene_v16.pdf %L hal-00276997 %U https://hal.science/hal-00276997 %~ UNIV-PARIS7 %~ ENS-PARIS %~ UPMC %~ LPA %~ CNRS %~ UNIV-LYON1 %~ UNIV-MONTP2 %~ LCVN %~ PSL %~ UPMC_POLE_2 %~ UNIV-MONTPELLIER %~ SORBONNE-UNIVERSITE %~ SU-SCIENCES %~ UDL %~ UNIV-LYON %~ UNIV-PARIS %~ ENS-PSL %~ SU-TI %~ ALLIANCE-SU %~ UM1-UM2
