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

A recently developed method of non-empirical wave-function calculation is applied to the calculation of ESR hyperfine coupling constants. In particular the effect of d orbitals on the computed values of these constants is investigated for I%$--and H2S'. In this note, we wish to report the use of the
