Induced absorption
WebStimulated or Induced Absorption: If an atom is initially in a lower energy state E 1, it can rise to a higher energy state E 2 by absorbing a quantum of radiation (Photon). The frequency of corresponding photon is given by = 𝐸2−𝐸1 ℎ This process is known as stimulated absorption or induced absorption. The WebPhoto-Induced Absorption Spectroscopy (PIA) Using PIA the dynamics of excited states in dyes, polymers and organic devices can be observed and thus basic processes like …
