We present a rotational analysis of the (0-0) bands of the visible d(3
) Phi -->, a(3) Delta and infrared b(3) Pi --> a(3) Delta systems of s
candium monofluoride which appear in the thermal emission. The wavenum
bers of 1240 lines observed in the Delta Sigma = 0 subbands of the two
systems are the subject of a global adjustment in which the electroni
c states involved are represented by adapted Hamiltonian matrices. Acc
urate rotational constants and energies at upsilon = 0 are obtained fo
r the three states. Reliable values of the spin-orbit splittings could
also be determined from the fits in spite of the nonobservation of sa
tellite subbands with Delta Sigma = +/-1. The three substates of b(3)
Pi all show significant Lambda-type doubling and the e/f parity of the
components could be determined. (C) 1995 Academic Press Inc.
