<jats:p>H-D exchange between deuterated surface hydroxyl groups and excited triplet acetone has been observed on porous Vycor glass, proceeding via a surface hydroxyl group-assisted photoenolization of acetone. This chemical process evidences that surface hydroxyl groups play a significant role in determining the fate of the excited triplet acetone adsorbed on Vycor glass by a strong hydrogen bonding.</jats:p>
