Tungsten Disulfide Raman Spectrum

Tungsten disulfide raman spectrum refers to raman spectroscopy analysis chart of tungsten disulfide (WS2). When a bunch of monochromatic light irradiating to tungsten disulfide, WS2 molecules will force incident light to disperse to produce a scattered light, which accounts 10-6~10-10 of the total intensity of the scattered light, The scattered light not only changes the propagation direction and the frequency, thus to produce the different frequency from the excitation light (incident light), and the scattered light is called Raman scattering. Raman spectrum can be used as the basis of qualitative analysis of WS2 molecular structure.
