We report the Y-Ba-Cu-O infrared (IR) transmittance, electron paramagnetic resonance (EPR) spectra and x-ray diffraction pattern evolution through transition of samples from oxygen disordered tetragonal O6 to orthorhombic O6.8 phase. The transmittance spectrum of the sample prepared by conventional technique and quenched in liquid nitrogen is considerably distorted by lattice defects. After thermal treatment, their concentration is reduced by interstitial oxygen redistribution and the spectrum acquires its natural shape. Further spectra evolution, considered as extra oxygen in-plane ordering, is in a good agreement with EPR and x-ray diffraction measurements. The possibility of Y-Ba-Cu-O films oxygen stoichiometry inspection by IR spectroscopy methods is discussed.
