We present a rotational analysis of the (0-0) bands of the visible d3Φ →, a3Δ and infrared b3Π → a3Δ systems of scandium monofluoride which appear in the thermal emission. The wavenumbers of 1240 lines observed in the ΔΣ = 0 subbands of the two systems are the subject of a global adjustment in which the electronic states involved are represented by adapted Hamiltonian matrices. Accurate rotational constants and energies at ν = 0 are obtained for the three states. Reliable values of the spin-orbit splittings could also be determined from the fits in spite of the nonobservation of satellite subbands with ΔΣ = ±1. The three substates of b3Π all show significant Λ-type doubling and the e/fparity of the components could be determined. |
