Fig. 8From: Water and magmas: insights about the water solution mechanisms in alkali silicate melts from infrared, Raman, and 29Si solid-state NMR spectroscopiesComparison between the concentration of OH groups measured with IR (LS4 and NS4 glasses) and 1H NMR (KS4 glass) data and that of OH groups bonded to Si determined with using 29Si NMR data for glasses with 17.6 mol % total H2O. The dotted lines are linear fits of the data. Error bars are given at the 1σ confidence intervalBack to article page
