Radiation damage in Thallous formate and acetate: Charge-transfer from Thallous ions

Abstract

Exposure of thallous formate to ⁶⁰Coλ-rays at 77 K gave a species exhibiting a multiline E.S.R. spectrum spread over about 1600 G which is interpreted in terms of $\text{C}\text{}$O₂^−: radicals undergoing strong interaction with two inequivalent thallous ions, a smaller interaction with another pair and weak interaction with a third pair. No Tl(II) centre was detected.

Thallous acetate also gave a multiline spectrum spread over about 500 G, which is assigned to H₂$\text{C}\text{}$CO₂⁻ raidcals interacting with two inequivalent thallous ions, and weakly with two others. A high-field feature assigned to Tl(II) was detected in this case.
