摘要
The B0(u)(+)-X0(g)(+) and B1(u)-X1(g) transitions of Se-80(2) and Se-78(2) are reinvestigated. Several new bands are reported, especially for the B1(u)-X1(g) system, their vibrational numbering being confirmed by isotope shift studies. The Franck-Condon factors and r-centroid values are evaluated. By correlating the theoretically computed intensities with observed values, the internuclear distance dependence of the electronic transition moments of these two systems is determined for the first time.
