Abstract
A van der Waals state of chromium dimers in an argon matrix has been detected via 458nm irradiation from an $Ar^{+}$ laser followed by an apparent intersystem crossing process. Resonance Raman study of this state with the 568nm line of a $Kr^{+}$ laser shows $w^{\prime \prime}_{e}=77.8cm^{-1}$ and $w^{\prime \prime}_{e}X^{\prime \prime}_{e}=0.01cm^{-1}$. Lifetime of this state is determined to be $\sim 0.5$ second, indicative of a spin-forbidden process involved in its relaxation.
