✦ Synopsis

Moiccular hydrogen. detected by gas-chromatographtc and mass-spectrometric measurements, was obtatrted by uradtatmg atth visible hght aqueous hydrochlondtc soluttons of [Rufbpy)3]*+ and tnvalent tttamum The actrve specres IS the 3Cf of IRu(bpy), I'+. u hrch ts quenched by TtfIlI) The suggested mechanism IS an electron transfer with Ti(II) formatlon The back reactton between [Ru@~y)3]~+ and T](D) IS hmdered by the very fast competrtrve reactton of Ti(Il) (not stable tn nctd aqueous solutrons) with H+. carrying to hydrogen evolutton.
