The fact that they tend to be fairly symmetrical (at least when they occur below the ionisation threshold) is related to their time characteristics from the lifetime widths and resonance energies, one can deduce that the giant resonances in metallic clusters are many-body oscillations undergoing several periods. Giant resonances in metallic clusters can truly be considered as plasmons, and relate quite clearly to surface plasmons in solids. 

The proceedings of a conference on metal-ammonia solutions have been published, featuring reviews of the physical properties of dilute and concentrated solutions, electrical, n.m.r., i.r., and Raman spectroscopic studies of diffusion, the solvated electron, kinetics, and solution structure."" Electron spin resonance in metallic Li-NHa systems has been investigated from 12 to 296 K. In the liquid solutions and in the cubic phase of Li(NH3)4 the conduction e.s.r. lineshapes are in agreement with theory. To a good approximation the solvated ions are the only spin scatterers in the liquid state. The paramagnetic susceptibility of liquid Li(NH3)4 indicates that the concentration of localized moments is low and they order antiferromagnetically below 20 K." ... 

In 1945 Calvin and Wilson (50) first suggested the importance of "benzenoid resonance in metal chelates of /ff-ketoenolates. In their classic paper, Stability of Chelate Compounds , Calvin and Wilson attempted to "determine the influence of certain structural factors upon the stability of the chelate complexes of divalent copper in which four atoms bound to the metal are all oxygen. After determining stability constants for the copper chelate complexes, the authors conclude for j8-diketonate ligands that "in addition to their character as bases, a benzenoid resonance effect involving copper plays a very important role in determining the stability of these compounds. The canonical forms which Calvin and Wilson considered important are shown below. 

Plasmonic resonances in metallic nanoparticles can be controlled by optimizing the nanoparticle topology, dimensions, and composition [1-3].
