Abstract

The EPR spectra of acidified solutions of Ti(III) were observed both above and below the freezing point. In the frozen glass, an axial spin Hamiltonian was found for the Ti(H2O)63+ complex with g∥=1.988±0.002 and g⊥=1.892±0.002. When warmed above −50 °C, broadening occurs which follows 1/T2=2.90×1014 e−ΔE/kT sec−1, where ΔE=1850±50 cm−1. This same broadening is followed for both the solution and frozen glass. The g values are explained assuming that the 1850 cm−1 value is the first excited orbital state energy, and the relaxation is explained as a resonant Raman process.
