Raman intensity 의미
WebbThe intensity of the D band vanishes in the bulk (as expected in HOPG) and only becomes visible at the edges, but interestingly the intensity is much bigger at armchair than zigzag edges. Note, that the intensity of the D' peak does not change with the shape of the edge. The explanation of this phenomenon is quite simple, as illustrated in Fig. 14. WebbThe Raman depolarization ratio ( ) is de・]ed for randomly oriented molecules in solution as the ratio of the Raman scattering intensities polarized along directions perpendicular (I? ) and parallel (Ik) to that of the incident radiation. In terms of r 1and r 2, is given by Equation [6]. ﾂｼ I?=Ik ﾂｼ 1:5ﾂｽﾃｰr 1r

WebbSpectroscopy is the study of the interaction between matter and light. There are different types of spectroscopy, which are typically named after either the used light source (e.g. IR spectroscopy) or the process of light-matter interaction exploited.
