  author={Lynn A. Silver and Edward M. Stolper},
Infrared spectroscopy has been calibrated to provide a precise and accurate method for determining the concentrations of molecular water and hydroxyl groups in hydrous albitic glasses. At total water contents less than 4 wt. %, most of the water is dissolved as hydroxyl groups; at higher total water contents, molecular water becomes the dominant species. For total water cont~nts above 4 wt. %, the amount of water dissolved as hydroxyl groups is nearly constant at about 2 wt.% and additional… CONTINUE READING
