摘要：

Using Raman spectroscopy we have monitored oxygen reordering processes in a room-temperature annealing experiment. We have discerned several structures corresponding to different oxygen coordination of Cu(l) in the basal plane by analyzing the line shape of the Raman band of apical-oxygen vibrations. We observed a chain-growing process with increasing annealing time followed by oxygen rearrangements in various orthorhombic superstructures.
