WebbFigure 2b shows the Raman of Rhodamine B/polyethylene and similarly Fig. 2a aims at the Raman of pure solid polyethylene. As one knows, the Raman modes of Rhodamine B are extremely fruitful and strong, especially in the region from 1200 to 1600 cm-1. There are abundant peaks whose relative Raman Intensity is ten times of that for polyethylene.
