LOW-LYING ELECTRONIC STATES OF THE SCF MOLECULE - ENERGIES OF THE A(3)DELTA,B(3)PI, AND A(1)DELTA STATES

Dispersed laser-induced fluorescence spectra of ScF have been recorded on a Fourier transform spectrometer. Most of the emission corresponds either to pure singlet or to pure triplet transitions, but excitation of perturbed levels of the D1Π state results in fluorescence to both triplet and singlet states. The triplet states of ScF were thus located in energy with respect to the singlet ground state. Constants are reported for the observed low-lying singlet and triplet states: A1Δ, a3Δ, and b3Π. © 1993 Academic Press, Inc.
