Raman spectroscopy of Carbon nanostructures is fundamental in characterising the morphology and the interaction of the nanostructure with the environment. This work provides an outline of the Raman Vibrational modes for graphitic structures starting from graphite fibres, to single-wall carbon nanotubes to multiwall carbon nanotubes and finally to Single- and Multi-layer Graphene. Following a brief outline of the dependence of the force constant on applied deformation, the stress induced changes in the Raman spectrum of graphitic structures are subsequently discussed with a view to elucidating the reinforcing ability of the CNTs in a matrix and assessing the stress transfer at the CNT matrix interface. The possibilities of employing CNTs as stress sensors in composite materials are also presented.
