In order to deepen in the knowledge of the vibrational properties of2-dimensional MoS2 atomic layers, a complete and systematic Raman scatteringanalysis has been performed using both bulk single crystal MoS2 samples andatomically thin MoS2 layers. Raman spectra have been measured undernon-resonant and resonant conditions using seven different excitationwavelengths from near-infrared (NIR) to ultraviolet (UV). These measurementshave allowed to observe and identify 41 peaks, among which 22 have not beenpreviously experimentally observed for this compound, characterizing theexistence of different resonant excitation conditions for the differentexcitation wavelengths. This has also included the first analysis of resonantRaman spectra that are achieved using UV excitation conditions. In addition,the analysis of atomically thin MoS2 layers has corroborated the higherpotential of UV resonant Raman scattering measurements for the non destructiveassessment of 2 dimensional MoS2 samples. Analysis of the relative integralintensity of the additional first and second order peaks measured under UVresonant excitation conditions is proposed for the non destructivecharacterization of the thickness of the layers, complementing previous studiesbased on the changes of the peak frequencies.
