Infrared OH absorption spectra were measured for a series of sodium aluminophosphate glasses. The absorption spectrum appears to be dependent on both alumina content and overall O/P ratio. The latter dependency cannot be explained by the conventional interpretation of the structural role of Al ions. Based on the latest studies on the role of Al ions in the phosphate glass, the influence of Al ions on the OH infared absorption spectrum is examined and explained.
