One example of the use of molecular mechanics is in investigating the mechanism of oxygen diffusion in albite, NaAlSisOg, a mineral related to zeolites. Experiments indicate that diffusion of oxygen in albite is faster in the presence of water. Molecular mechanics calculations show that the activation energy for OH- diffusing through the solid is lower than that for diffusion for O2-. [Pg.15]
