Electronic States of Lanthanum Monoiodide: Preliminary Data from High-Resolution LIF Spectroscopy.
Fluorescence spectra of lanthanum monoiodide excited by the Ar+ 501.7-nm laser line have been observed and analyzed. Seven (sub)states are characterized. Preliminary rovibrational data are obtained for the four low-lying states (I-IV). The first two can be ascribed as X1Sigma and a3Delta: III does have Omega = 1, and IV is possibly 1Delta. The 11 laser-excited levels are tentatively grouped into three entities. Copyright 1998 Academic Press.
