THE QUENCHING OF THE IODINE FLUORESCENCE SPECTRUM [PDF]

open access: bronzeCanadian Journal of Chemistry, 1958
The quenching of the iodine fluorescence spectrum by various inert gases and oxygen has been studied with a view to obtaining information on the efficiencies of vibration energy transfer processes in this system. Preliminary results here presented are in agreement with earlier work of Rössler and Eliaschevich and indicate that the transfer processes ...

Magnetic quenching of fluorescence

Chemical Physics Letters, 1977
Abstract The direct and indirect mechanisms for the magnetic enhancement of radiationless decay processes are described, and used to account for the experimental observations of the magnetic quenching of fluorescence from carbon disulphide, glyoxal, and nitrogen dioxide.

Quenching of NO2 Fluorescence

The Journal of Chemical Physics, 1966
Quenching constants for NO2 fluorescence were obtained for 13 different inert gases. Quenching cross sections range from 1/25 to 1/2 of gas kinetic and increase with increasing molecular complexity, and dipole moment. No unusual resonance effect for quenching by ground-state NO2 was found.

Detection of oxygen by fluorescence quenching

Applied Optics, 1985
The incorporation of an aromatic hydrocarbon fluorescent compound into silicone allows utilization of fluorescence quenching as a mechanism to measure molecular oxygen concentration in the composite matrix. Excitation and emission spectra of the aromatics change in agreement with the Franck-Condon model when the universal solvent is benzene ...
