A bstract : Raman spectroscopy is reviewed with particular emphasis placed on its application to gas hydrates. Experimental examples discussed include studies of the totally symmetric C‐H stretching vibration ν 1 ( A 1 ) of methane in both synthetic and natural hydrate samples (from the JAPEX/JNOC/GSC Mallik 2L‐38 research well); a comparison of the coupled O‐H vibrations of water in the host lattice of CH 4 hydrate and ice I h at low temperature; and local structural details of the relaxation of the hydrogen‐bonded water on crystallization to structure II hydrate of amorphous tetrahydrofuran (THF) aqueous solutions. This paper is intended to be an introduction to Raman spectroscopy with specific examples from research at the National Research Council of Canada, and is aimed at those who wish to apply the technique as a tool to investigate gas hydrates.
