Cm or C70 reacts with 2-aminoisobutyric acid and cyclohexanone in chlorobenzene at refluxing through 1,3-dipolar cycloaddition to give [6O]fulleropyrrolidine 1 or [70]fulleropyrrolidine 3 which can be oxidized with MCPBA at room temperature to yield stable nitroxides 2 or 4. The compounds 1 and 3 we

The published "C NMR spectra of CGO give an absolute carbon shielding of u=43 ppm, i.e. 14 ppm less than for carbon in benzene. Extrapolation from ab initio coupled Hartree-Fock calculations with the origin of the vectoi potential at the nucleus gives a-46 ppm as the basis-set limit. Minimal basis a
Magnetic properties of monoradicals and diradicals based on thienyl-substituted nitronyl nitroxide (NN) were investigated by measuring temperature and magnetic-field dependences of magnetization. The magnetic behavior of the monoradical 3-benzo[b]thienyl NN (3-BTHNN) is interpreted in terms of the q
The magnetic and superconductivity properties of rubidium-doped C60 were studied. The temperature dependence of the irreversibility line H'(T') as determined by SQUID magnetization measurements gave a power law (n ,~ 2) scaling of the reduced relative irreversibility temperature with irreversibility
