13C hyperfine coupling constants of the MuC6o radical have been measured by muon level-crossing spectroscopy, using a dilute solution of 99% enriched ~3C6o in decalin. The signs as well as the magnitudes of the hyperfine constants were determined. The results range from 52.6 to -25.4 MHz and support

β¦ Synopsis
The 13C hyperfinc splitting constants of the tetrachloro+benzosemiquinone radical anion are measured for naturally occurring 13C nuclei in all the possible positions in the molecule. 'Their ass@unent is based on the linewidth.andysis of the single hyperfiie components and this is disc&d with reference to the reported spin density distribution ino-semiquinones.

The EPR signal intensity of photochemically formed HCm depends on the oxidation potential of other radicals involved, suggesting that HCa is formed by reduction of Cm followed by protonation. The 13C hyperfine couplings of forty carbons are resolved, demonstrating that the electron spin is distribut
