Abstract
A precision, resonance absorption measurement has been made of the ratio of the magnetic moments of and . The experimental ratio is . This result, when compared with the value observed by Berman for the ratio of hyperfine structure separations in the state, , 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 compared to 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.
