    A solid-state (CP-MAS)13C nuclear magnetic resonance study of selected photo(thermo)chromic spiro-(indolinonaphthoxazine)s

    Liquid and solid-state13C NMR data are reported for three photo(thermo)chromic spiro-(indolinonaphthoxazine)s,1–3. The isotropic13C chemical shifts are almost identical in the solid state and in solution. Therefo...

    Studies on Some Trifluoromethyl Nitroxide Radicals by EPR Spectroscopy

    The hyperfine splitting by 17O in (CF3)2N170• is 23.6 G which is appreciably larger than the 19.4 G reported for [(CH3)3C] 2N170• and indicates that the former radical has a relatively high spin density on oxygen...

    Quantum Mechanical Tunneling in Free Radical Reactions

    Examples of free radical reactions are described for which convincing evidence for quantum-mechanical tunneling has been reported. They include: H-atom abstraction reactions by thermalized methyl radicals and ...
