Clathrate hydrates are icelike structures in which water molecules form cavities enclathrating many possible types of guest molecules. Among most important representatives of this group of solid structures are methane and carbon dioxide clathrate hydrates. The first one is widely present in Nature and in the future will serve as an energy resource. Carbon dioxide clathrate hydrate may on the other hand serve as a storage reservoir for this green house gas providing cheap way to lower its emission to atmosphere. Those are just two of many more important issues that catalyse growing interest of scientific world in clathrate hydrates. Characterisation of their properties is crucial to develop technologies, that will enable us to utilize their manifold possible applications. During this presentation I will discuss some of my investigations concerning NMR properties of clathrate hydrates.
