Weltner and D. McLeod, J. Chem. Phys. 69, 3188 (1965). en_US dc.description Author Institution: en_US dc.description.abstract An apparatus for the measurement of magnetic circular dichroism (MCD) and UV-visible absorption spectra of matrix-isolated high temperature species has been constructed. The spectra of Group IVb diatomic oxides have been examined. TiO was prepared by vaporization of $TiO_{2}$ at $\sim 2300^{\circ} K$ and trapped in argon at $14^{\circ}$K. The absorption spectrum was similar to that of $Weltner^{1}$ - the $\gamma , \gamma^{\prime}$ and $\alpha$ systems were observed. The MCD spectra showed no temperature dependence in the range of 14 to $24^{\circ} K$ which confirms the assignment of the ground state as $^{3}\Delta_{r}$(zero C term). The absence of MCD for the $\alpha$ transition also confirms its assignment as $^{3}\Delta 1\leftarrow\ ^{3}\Delta 1$ (A term is predicted zero). The spectra of zirconium oxide and hafnium oxide will also be discussed. en_US dc.format.extent 81660 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title MAGNETIC CIRCULAR DICHR0ISM OF MATRIX ISOLATED GROUP IVb DIATOMIC METAL OXIDES en_US dc.type article en_US
