Abstract
The technique of selectively detected fluorescence excitation spectroscopy has used to record the 0-0 and 1-1 bands of the $F^{1}\Phi-A^{1}\Delta$ transition of ScF at a resolution of $0.03 cm^{-1}$. Perturbations in the $F^{1}_{\Phi}$ state caused by interactions with the $h^{3} \Pi_{2}$ state were analyzed. With used of a method based of Franck-Condon factors, the vibrational numbering in the perturbing $h^{3} \Pi_{2}$ state was estimated. The principal constants ($in cm^{-1}$) obtained form recent and $previous^{1}$ analyses are: [FIGURE] Experimentally determined parmeters are in excellent agreement with the {ab initio} $calculation^{2}$.
