Abstract A Raman spectroscopic investigation of the SiO2-clathrate melanophlogite was undertaken to investigate the enclathrated molecules. The Raman spectra show the presence of N2, CO2, and CH4 molecules based on the observation of their normal stretching modes. An analysis of the spectra, together with single-crystal X-ray results (Gies 1983), demonstrates that the molecules are located in structural cages. Most of the CH4 is partitioned into the smaller nearly spherical [512] cage, while…

TLDR
The unusual increase of the CH3/SiO2 clathrates EPR spectral width with temperature over approximately 120 K has its origin in repeated angular momentum vector alterations due to frequent collisions with the clathrate void walls between periodical free rotation periods.
