Abstract
The paramagnetic resonance of Mo5+ in liquid solution with two different (chloride and thiocyanate) complexes has been observed. In each case, a hyperfine interaction due to the odd isotopes of molybdenum was observed, in addition to the contribution of the zero-spin isotopes which yield a single line at the center of the spectrum. Upon freezing the solutions, the resonance spectra may be described by spin Hamiltonians possessing axial symmetry. The averages of the g tensor and the hyperfine tensor agree very well with the measured values obtained with the liquid solutions.
