Results are briefly compared with characteristics of present day lasers. Molecules have various states referred to as energy levels. The underlying principle of atomic absorption spectroscopy (AAS) is the absorption of energy exclu-sively by ground state atoms while they are in the gaseous form. 1.12. Fluorescence and phosphorescence are two forms of photoluminescence used in modern research and in practical applications. The Fluorescence Process! 454: tion of emission spectrum 457 Origin of emission spectra 458 The emission process . Cold vapour atomic fluorescence spectroscopy (CVAFS) is a subset of the analytical technique known as atomic fluorescence spectroscopy (AFS). Generally, the species being examined will have a ground electronic state (a low energy state) of interest, and an excited electronic state of higher energy. Electron Spin 3.

Among others were Zeeman's discovery of the splitting of atomic spectral lines in an applied magnetic field (1896) and its subsequent explanation by H.A. Chapter 9 Atomic Absorption And Atomic Fluorescence ... PPT. Emission Spectroscopy Using Plasmas, Arcs or Sparks • Inductively Coupled Plasma (ICP) • Direct Current Plasma (DCP) • Arcs and Sparks Plasma = hot ionized gas or region with such a significant number of charged species as to dramatically change its electrical & magnetic properties. Like atomic absorption, ground state atoms created in a flame are excited by focusing a beam of light into the atomic vapor. Theory for Time-Dependent Solvent. External Conversion 5.4.
