Query: Probing electronic excitations in mono- to pentalayer graphene by
  micro-magneto-Raman spectroscopy   We probe electronic excitations between Landau levels in freestanding
$N-$layer graphene over a broad energy range, with unprecedented spectral and
spatial resolution, using micro-magneto Raman scattering spectroscopy. A
characteristic evolution of electronic bands in up to five Bernal-stacked
graphene layers is evidenced and shown to remarkably follow a simple
theoretical approach, based on an effective bilayer model. $(N>3)$-layer
graphene appear as appealing candidates in the quest for novel phenomena,
particularly in the quantum Hall effect regime. Our work paves the way towards
minimally-invasive investigations of magneto-excitons in other emerging
low-dimensional systems, with a spatial resolution down to 1$~\mu$m.
