Baskan, M.

The observed paramagnetic species were attributed to the CH3CHCOOC2H5, -CH2CHCOOH and -CH2CHCOOCH3 radicals, respectively. Hyperfine structure constants and g-values were determined for these three radicals. Some spectroscopic properties and suggestions concerning the possible structure of the radicals were also discussed.
