✦ Synopsis
Atomic force calculations and the optimization of atomic structure in the ground state have been made in the cluster version of the full-potential linear muffin-tin orbital method. Relaxation along atomic forces in the ground state enabled us to estimate the main parameters of the atomic structure and total energy in the ground state of fullerene epoxide derivatives C~O and Cs~O2, obtained recently in the reaction of C.~ with ozone in toluene. We found the Ca~O isomer, with the oxygen atom bridging the 6,6 carbon bond, to be more stable than that with the oxygen atom bridging the 6,5 bond. The most polar isomer of Ca)O2 with the oxygen atoms placed at the same 6,6 ring, is found to have the lowest energy compared with other bridgings of oxygen atoms, in agreement with experimental data.
