Abstract
Abstract Birefringences of oriented aggregates of Na-montmorillonite expanded in sodium chloride solutions were measured and compared with birefringences calculated from Wiener's equation. The difference between the calculated and the observed values is nearly constant in the region of swelling values 10–20 X. It is inferred that the difference comes from the birefringence of the polymolecular water layers and that it is evidence for a specific anisotropic structure. Anisotropy is also shown in some intercalated organic polymolecular films.
