Raman spectroscopy of graphene has been intensively studied since it was discovered in 2004.Here we report the observation of breathing Raman modes in low-frequency range of 100~200 cm-1 in misoriented few-layer graphene on SiO2/Si substrate.Two dominant Raman modes are identified lying around 120 cm-1 and 182 cm-1.
