Quantum chemical SCF calculations on a double four-membered silicate ring model, H Si 0 s s \*e, of silica yield a theoretical estimate of 1400 f 25 kJ/mol for the heat of deprotonation of surface silanol groups, in close agreement with a value of 1390 \* 25 kJ/mol inferred from spectroscopy. The pr
