Kinetics of Nitrogen Dioxide Fluorescence [PDF]

The Journal of Chemical Physics, 1969
The fluorescence lifetime and intensity of gas-phase nitrogen dioxide (2B1) have been measured as a function of excitation wavelength, fluorescence wavelength, and pressure (0.5–50 mtorr). The phase-shift method was used; this technique allows lifetime measurements to be obtained with signal intensities of 100 counts per sec and lower.
