Absorption of the Excitation Energy

Instead of making use of direct absorption of the excitation energy by the molecule being analyzed it is possible (as is the case of oxygen... [Pg.177]

Concentration At high concentrations fluorescence emission l ecomes non-linear due to self-absorption by the sample itself or complete absorption of the excitation energy before it reaches the cell center. High fluorescence Intensity may overload the photomultiplier tube which returns slowly to its normal operating conditions and misrepresents the actual fluorescence signal until restabilized. [Pg.809]

Absorption of the Excitation Energy 2.3.1 Optical Absorption Spectroscopy... [Pg.12]

Neglecting the filled low-energy o-orbitals, the electronic configuration of the lowest electronic state (the ground state) is tt2n2. Photon absorption of the appropriate energy results in excited-state configurations by promotion of one electron from an occupied molecular orbital... [Pg.13]

The excitation of a molecular entity due to absorption, successively or simultaneously, of two photons. If successively, the species that absorbs the second photon still has some of the excitation energy imparted by the first photon. [Pg.690]

The photon hvx emitted in a radiating transition is reabsorbed with a certain probability by another molecule X or Y. By absorbing the photon the molecule makes a transition into the excited states X and Y, respectively. Thus the Y molecules are excited only by the radiating and nonradiating transfer of the excitation energy. The photons hvY emitted in a radiating transition which do not undergo self-absorption leave the scintillator. [Pg.593]
