Kenneth S. Thomas,Harold J. McMann in a random direction with a random phase, conventional light sources are intrinsically chaotic. The laser is a completely different light source, because it is based on stimulated emission instead of spontaneous emission, which means that atoms emit in a cooperative way, generating a monochromatic

Kenneth S. Thomas,Harold J. McManns is displayed as a mutual “shielding” of chromophores from light and the effect therefore is termed “screening hypochromism”. The hypochromic cross section for identical dipoles was calculated from probabilities of absorption in a stack. The screening leads to a reduction in the average extinction

Dans le meilleur des cas, ces échelles sont bien séparées, mais il peut arriver parfois qu’elles se recouvrent partiellement. Du point d
