Abstract

Fluorescence emission scans have been made of bands of the NO ß-system (B2Π-X2Π) following laser excitation of v′ = 0, 1, 2, 3, and 7. Time dependent decays furnished the radiative lifetimes for these levels. The band intensities were used together with calculated Franck-Condon factors and r-centroids to derive an empirical electronic transition moment which varies with internuclear distance. The functional form agrees well with that deduced from an analysis of chemiluminescent spectra of several bands,¹ and with lifetime trends measured here and previously.²
