Resonance light

While neat-resonant light exerts both scattering forces and dipole forces on single atoms, similar forces ate also exerted on larger dielectric objects.

Electronic Structure. Measurements of paramagnetic susceptibility, paramagnetic resonance, light absorption, fluorescence, and crystal structure, in addition to a consideration of chemical and other properties, have provided a great deal of information about the electronic configuration of the aqueous actinide ions in which the electrons arc in the 5/ shell. There are exceptions, such as U2S3, and subnormal compounds, such as TI12S3, where 6d electrons are present. 

Up to this point, we have been considering the absorption properties of Au nanoparticles and the significance of Cabs in colorimetric or photothermal applications. However, colloidal Au particles are also famous for resonant light scattering, which depends on CJca.109,110 The earlier description of C, is dominated by Cabs and intended only for smaller nanospheres (r < 20 nm). Cext is more correctly described as the sum of Cabs + Csca ...

The form of the result (18.23 ) suggests an interpretation of resonance light scattering as a 2-stage process—preparation of the intermediate level s followed by emission out of this level. We will see, however, that such a picture is too simplistic. For example, if several intermediate levels s contribute to the light scattering an...
