The Half Field Line of Tetrakis(Dimethtlglyoximato)Dicopper(II) in Glasses

Abstract
We have reported recently the finding1 of triplet state EPR spectra in glasses of tetrakis(dimethylglyoximato)dicopper(II) in ethyl alcohol (a.) at 77°K. Now we wish to report the resolution of the half field band (HMIN) and the observation of metal and ligand nuclear hyperfine structure on this band. In previous studies of half field lines, the metal nuclear hyperfine has been sufficiently2,3,4 clear to interpret only in a few cases and the ligand nuclear hyperfine has never been observed before.
