Abstract
Absorption spectra of these molecules, observed between 200 and $4800 cm^{-1}$ in neon and argon matrices at 4K were assigned to the lowest $3^\Pi-X^{3}\Sigma^{-}$ electronic transition.1 In all five cases, the Franck -Condon envelope of vibrational bands allowed $T_{oo}, \omega_{e}^{\prime}, \omega_{e}^{\prime}, x_{e}^{\prime}$ 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 $Si_{2}$ to $Sn_{2}$.
