✦ Synopsis

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 a ˜3B 1 R X ˜1A 1 band system silicon difluoride, SiF 2 , has been completed. Spectra were taken under pyrolysis-jet conditions at a resolution of ca 0.04 cm 01 . The rotational (A, B, C), centrifugal distortion (D k ), spinrotation (a, a 0 ), and spin-spin (a, b) constants for the upper n 2 state are reported. An effective r 0 structure has been calculated for each upper vibronic state. Some minor intensity anomalies have been observed in the spectra of both bands.
