Resonance Raman spectra have been recorded for bromine and iodine supported on the surface of porous Vycor glass. They show that the halogens are mainly physisorbed on the Vycor glass. Other features indicate the presence of polyhalide species of type X 3 − . When the amount of polyhalide is large, we observe peaks which can be attributed to a halogen molecule coordinated to a Lewis base, which is probably X 3 − .
