Hi, I was wondering if someone could explain, in their own (simple) words, what the scattering spectrum of a nanomaterial is. For example, suppose we have a chain of several spherical nanoparticle. How would you interpret this graph: http://ajpheart.physiology.org/content/293/6/H3379/F9.small.gif I know that in a typical experiment, one shines a laser of a given wavelength, and observes the optical response. But what is this response precisely in this case? How does it relate to scattering? Any help would be appreciated. Thanks!
