C. Effantin et al., Electronic states of lanthanum monoiodide: Preliminary data from high-resolution LIF spectroscopy, J MOL SPECT, 192(2), 1998, pp. 394-398
Fluorescence spectra of lanthanum monoiodide excited by the Ar+ 502.7-nm la
ser line have been observed and analyzed. Seven (sub)states are characteriz
ed. Preliminary rovibrational data are obtained for the four low-lying stat
es (I-IV). The first two can be ascribed as X(1)Sigma and a(3)Delta: III do
es have Omega = 1, and IV is possibly (1)Delta. The 11 laser-excited levels
are tentatively grouped into three entities. (C) 1998 Academic Press.
