The local environment about oxygen atoms in the CuO{sub 2} plane in YBa{sub 2}Cu{sub 3}O{sub 7} single crystals has been investigated by orientation-dependent x-ray absorption fine structure (XAFS) spectroscopy at the O ls edge using bulk-sensitive fluorescence-yield-detection method. Within experimental accuracy ({plus_minus}0.03 {Angstrom}) no structural change in local ordering about oxygen atoms in the CuO{sub 2} plane at 90 K has been detected. 14 refs.
