Infrared and Raman spectroscopy were used to establish the presence and interactions of guest molecules enclosed in the SiO 2 -clathrasil compound Dodecasil 3C. X-ray powder diagrams showed an expansion of the crystal lattice that varied with the siz

Species included in clathrasils have been analyzed by quantitative IR spectroscopy. In the case of dodecasil 3C, with benzene or piperidine as guest molecules, results showed that only one out of 16 or 8 suitable cavities in the clathrasil structure

13CO3 −- substituted compounds with the aragonite structure show a fine structure of the out-of-plane vibration in the infrared spectra. A simple quantum mechanical model of coupled oscillators is developed to describe quantitatively the observed s

The biochemical effects of methyl chloride were investigated in tissues of F-344 rats and B6C3F1 mice (both sexes). Activities of GST were 2-3 times higher in livers of male B6C3F1 mice, compared with those of female mice, and with rats of both sexes
