Fig. 3. Simulated infrared (IR; a, c, e and g) and Raman (b, d, f and h) spectra of SnS2 (a and b), Pnma SnS (c and d), π-cubic SnS (e and f) and Sn2S3 (g and h). The spectral lines have been broadened using calculated 10 K (blue), 150 K (red) and 300 K (orange) linewidths. For clarity, the simulated spectra at the latter two temperatures have been enhanced by 2× and 3×, respectively.
