Abstract

Absorption spectra of these molecules, observed between 200 and $4800 c m −1$ in neon and argon matrices at 4K were assigned to the lowest $3 Π − X 3 Σ −$ electronic transition.1 In all five cases, the Franck -Condon envelope of vibrational bands allowed $T o o, ω e', ω e', x e'$ to be determined, A Zeeman effect on this, transition was detected in magnetic fields up to 4T. The transition from case (a) to case (c) is considered as the spin-orbit coupling increases from $S i 2$ to $S n 2$ .
