    "abstract": "We present an experimental spectroscopic study of large random colloidal\naggregates of silver nanoparticles undergoing local restructuring. We argue\nthat such well-known phenomena as strong fluctuation of local electromagnetic\nfields, appearance of \"hot spots\" and enhancement of nonlinear optical\nresponses depend on the local structure on the scales of several nanosphere\ndiameters, rather that the large-scale fractal geometry of the sample.",
