Indeed, as shown in Figure 6(a), which presents several colored curves corresponding to accumulated measurements taken at different points in the grid visible in Figure 5(b), the Raman spectrum collected on the contaminated front side is not homogeneous on the surface and shows pronounced new broad bands with respect to that realized on the Beautifil II before the contamination (green curve in Figure 4).
