 Title: MAGNETIC CIRCULAR DICHROISM OF MATRIX ISOLATED GROUP VB DIATOMIC METAL OXIDES Creators: Brittain, R.; Powell, D. L.; Vala, Martin Issue Date: 1979 Publisher: Ohio State University Abstract: The magnetic circular dichroism of Ta0 matrix isolated in argon has been observed in the temperature range $10-24^{\circ}$K. Overlapping vibrational bands of the K, L, and H transitions, previously reported by Weltner and $McLeod^{1}$, were found to have C terms of opposite sign. The assignments of Cheetham and $Barrow^{2}$ of the ground state to $^{2}\Delta_{3/2}$ and the L and M states to $^{2}\pi_{1/2}$ and $^{2}\Phi_{5/2}$, respectively, are confirmed by our results. The MCD and absorption spectra of VO and NbO will also be discussed. Description: $^{1}$W. Weltner, JR., and D. McLeod, JR., J. Chem. Phys. 42, 882 (1965). $^{2}$C. J. Cheetham and R. F.
