Abstract
The authors review evidence, from NMR of Cu-63 and O-17 atoms in the C uO planes, concerning the spin and orbital pairing of the superconduct or YBa2Cu3O7. It shows that the NMR data in the superconducting state require, a spin-singlet pairing state. It is consistent with orbital d -wave pairing, but not with a conventional orbital s-wave pairing. Whe ther or not other types of orbital pairing states (e.g. anisotropic s- state) can explain the data can only be judged when those theories are used to calculate the NMR properties.
