Optical Properties of Colloids
... To increase the resolving power of a microscope, the wavelength of the radiation used must be reduced. Electron beams can be produced with λ ~ 0.01 nm and focused by electric or magnetic fields, which act as the equivalent of lenses. However, the resolution of an electron microscope is limited ...

... Here (3) is a material property that governs the nonlinear response of a medium and all nonlinear processes occurring in that medium. It is therefore important to notice some aspects of (3), even before starting a treatment of specific nonlinear processes. 1) A general expression of the third orde ...

Computational Spectroscopy
... In practice DFT calculations are not done just as a single step, but uses an iterative approach analogous to the Hartree-Fock self-consistent field method. The Becke 3 - Lee, Yang, Parr (B3LYP) functional is one of the most popular. Many new functionals are reported in the literature. The computer t ...

Spectroscopy and the Electromagnetic Spectrum
... The electromagnetic spectrum is arbitrarily divided into regions, and it is clear that the familiar, vis portion of the spectrum (i.e., 390–750 nm) constitutes only a small section of the full spectrum. The vis region is flanked by the higher-energy, ultraviolet (UV) and the lower-energy, infrared ( ...
