Electronic States of Scandium Monoiodide

The many electronic transitions observed in high-resolution spectra of the fluorescence of scandium monoiodide following excitation by Ar+ and Kr+ laser lines have been extensively analyzed. Equilibrium vibrational and rotational constants are obtained for the six lowest electronic states. Spin-orbit constants in a3Delta and b3Pi are also determined. The laser-excited levels are regrouped into two electronic states, of 1Pi and 3Pi symmetries, for which molecular constants are derived. Copyright 1997 Academic Press. Copyright 1997Academic Press
