Abstract

A precision, resonance absorption measurement has been made of the ratio of the magnetic moments of Tl205 and Tl203. The experimental ratio is μ205μ203=1.009838±0.000001. This result, when compared with the value observed by Berman for the ratio of hyperfine structure separations in the P122 state, Δν205Δν203=1.00974±0.00003, establishes the reality of effects attributable to the finite nuclear size.

Shifts of about 0.2 percent have been found in the thallium resonance position in Tl+3 compared to Tl+1 compounds. The resonance shifts in aqueous solutions varied linearly with the anion concentration. Complex formation and interionic electronic exchange interactions, respectively, account qualitatively for the observed effects.
