63'65Cu NMR and NQR studies of YBa2Cu307\_ b are described for compositions, 6, of 0.0, 0.3, and 0.9. Spin-lattice relaxation rates in YBazCu307 reveal significantly different electron dynamics at the two Cu sites in both the normal and superconducting states. In YBa2Cu306.7, the relaxation rates of
