摘要

The time dependent behavior of molecular nitrogen ions has been investigated following pulsedphotoionization of near atmospheric pressure N2 using multiphoton laser techniques and kineticmodeling. Multiple fluorescence bands, some unreported previously, with various temporalbehaviors were observed after ultraviolet laser photoionization of N2(X 1Σg). The initial N2ionization was generated via resonance-enhanced multiphoton ionization with focused radiation inthe 275-290 nm range, where several resonant transitions are accessible. The observed opticalfluorescence bands appeared to be unique to the near-atmospheric pressure N2 condition and wereshown by the evidence in this work to be the result of collisional formation and recombination ofN. Measured time dependent fluorescence spectra during and after pulsed laser photoionization ofN2, together with a coupled rate equation model, allowed for the determination of the absolutedensities of N2+ and N4+ as these species evolved.
