Progress has been made in the study of the electronic spectrum of the scandium monochloride molecule. A number of transitions are interpreted, involving five new electronic states, b(1) 3 P, A(1) 1 D, (1) 1 F, (2) 1 D, and (3) 1 D, for which molecular constants are determined.

β¦ Synopsis
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 a 3 D and b 3 P are also determined. The laser-excited levels are regrouped into two electronic states, of 1 P and 3 P symmetries, for which molecular constants are derived.

Fluorescence spectra of lanthanum monoiodide excited by the Ar Ο© 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 X 1 βΊ and a 3 β¬: III does have
Rotational analyses have been carried out on eight thermically excited emission bands of the infrared B 1 P r X 1 S / system of scandium monoiodide between 4000 to 5000 cm 01 , recorded by Fourier transform spectrometry. Rotational constants and energies are obtained for X 1 S / ( Β£ Γ 0, 1, 2 ) and
