Abstract
The absolute charges of atoms in all sites of the YBa2Cu3O7 lattice were determined using Mössbauer data for 67Cu(67Zn) and 67Ga(67Zn) isotopes, NMR/NQR data for 17O and 137Ba isotopes, and calculations of the lattice electric-field gradient. The obtained charge distributions correspond to a hole occurring predominantly in the sublattice of chain oxygen.
