Abstract
The electronic spectroscopy of $I_{2}$ and IBr, isolated in solid rare gas matrices has been studied using time and wavelength resolved fluorescence techniques. Argon isolated $I_{2}$, excited at a wavelength of 193 nm, showed a broad feature at about 380 nm, that has a very short life-time (= 20 ns). This transition has been tentatively assigned as the $D(^{3}\Pi_{2g})-A(^{3}\Pi_{2u})$ system. Ar, Kr and Xe isolated IBr, excited at a wavelength of 532 nm, exhibited both $A(^{3}\Pi_{1})-X(^{1}\Sigma)$ and $A^{\prime}(^{3}\Pi_{2})-X(^{1}\Sigma)$ systems. The life-times of these transitions decrease with increasing atomic number of the host. Spectral and temporal analyses will be discussed.
