Figure 4: Polarization dependence of Raman modes and their pressure dependence.

From: Unusual lattice vibration characteristics in whiskers of the pseudo-one-dimensional titanium trisulfide TiS3

Figure 4

Angle-resolved Raman spectroscopy (2D contour plots) for all the Raman peaks in the (a) normal (E || D) and (b) orthogonal (E⊥D) configuration. E and D represents the excitation direction and detection direction, respectively. (c) Evolution of Raman spectrum in orthogonal configuration displaying similar pressure-dependent trends and dω/dP values.
