Diamagnetic peroxo/hydroperoxo

An additional, independent estimate of the concentration of paramagnetic superoxo and diamagnetic hydroperoxo-/peroxo-titanium species was made from magnetic susceptibility measurements using a Lewis coil force magnetometer (52). The gram-susceptibility of Ti in TS-1 + H2C>2 was estimated to be 5.5 X 10-6 emu/g, which corresponds to an effective magnetic moment of... [Pg.69]

B.M. If all the Ti ions in the sample had formed superoxo species upon interaction with H2O2, the effective magnetic moment should have been 1.73-1.78 B.M. The concentration of superoxo-Ti species is, thus, about 45% of the total Ti, comparable to the values found by EPR (55%) and electronic spectroscopies. The remaining fraction is, presumably, the diamagnetic hydroperoxo-/peroxo-Ti species. [Pg.69]
