A combination least-squares and band contour analysis of the 2(1)0 and 2(2)0 bands of the laser-induced phosphorescence spectrum of the ã 3B1 <-- &Xtilde; 1A1 band system silicon difluoride, SiF2, has been completed. Spectra were taken under pyrolysis-jet conditions at a resolution of ca 0.04 cm-1. The rotational (A, B, C), centrifugal distortion (Deltak), spin-rotation (a, a0), and spin-spin (alpha, beta) constants for the upper nu2 state are reported. An effective r0 structure has been calculated for each upper vibronic state. Some minor intensity anomalies have been observed in the spectra of both bands. Copyright 1998 Academic Press.
