Raman Spectroscopy:

Raman spectra at different temperatures can also be done to understand the effect of temperature on the vibrational properties of the materials. For example, Figure 39.04 depicts the in-situ temperature dependent Raman spectra of graphene layers.

Figure 39.04: In situ temperature-dependent Raman spectra of 2+2 r-f4LG. (a) Temperature-dependent Raman spectra of shear mode with both Stokes (S) and anti-Stokes (AS) lines, (b) Sample local temperatures estimated from intensity ratio of S/AS as a function of thermal chamber temperatures, (c) Positions and FWHM of Stokes shear mode as a function of temperatures [1].
