Abstract
The time-resolved and dispersed fluorescence of NO2 excited by an N2-laser pumped tunable dye laser was investigated. A pseudocontinuum similar to that obtained by Sakurai and Broida (cw Ar+ and Kr+ lasers) was observed with excitation around the Huber-Douglas bands (454.5 nm). The decay times revealing the red shift were measured at 5 nm intervals (475–650 nm) with 10 nsec time resolution. The wavelength dependency is interpreted by means of the step ladder model by Donnelly et al. The signal-to-noise ratio is greatty improved by taking the average of 1000 laser shots for the fixed wavelengths.Keywords
