Abstract

A nitrogen laser pumped tunable dye laser has been used to observe the three‐photon ionization of NO through a two‐photon resonance with the C^2^II state. Fluorescence is also observed from this state. The wavelength dependence of both signals have been measured. A reaction mechanism is postulated, which includes the initial two‐photon excitation of the C^2^II state as the rate‐limiting step. This mechanism predicts the observed second‐order intensity dependence of the ionization signal and shows that the simple rate equation treatment is valid in this system.
