Raman scattering is shown to yield information on the orientation of crystallographic axes, labile oxygen concentration, and degree and nature of the disorder of oriented YBa2Cu307 _ δ films. A correlation is established between the temperature of the transition to the superconducting state, Tc0, and the width of the line at ν_ s == 500 cm ~1.
