Abstract
The e.s.r. spectra of copper(II) dialkyldithiocarbamates in frozen solutions of chloroform containing small amounts of other solvents have been shown to give a well resolved signal at g ca. 2 and 77°K superimposed on a broader line while at the same instrument gain a signal at low field is observed. The broad signal at g ca. 2 and the lines at half-field have been interpreted as arising from ΔM= 1 and ΔM= 2 transitions, respectively, occurring as the result of dimer formation. Solution of a spin Hamiltonian including dipole–dipole terms and the application of computer simulation of the line-shapes have enabled the distance of 4·7 ± 0·4 A between the copper(II) ions in the dimer to be determined. A structure of the dimer is considered which would be compatible with this distance.
