Abstract
It is worthwhile to note that hydrogen atoms sructually bound to minerals can interact with network-forming oxygen atoms in minerals through hydrogen-bonding. This suggests the significance of chemical state of hydrogen on studying the role of hydrogen to the change in physicochemical and elastic properties of materials in the mantle. IR spectroscopy provides us with much information on the chemical states of OH species contained in these H-carrying minerals. This paper reviews the advantages of IR spectroscopy to the speciation of OH in minerals, quantitative analysis of hydrogen and determination of direction of OH dipole moment in a single crystal along with the several attentions to be paid on thepractical experimantal procedures. Furthermore, speciation of OH in the olivine-wadsleyite-ringwoodite system and its potential role on mantle dynamics is mentioned in detail. It is a definite fact that IR spectroscopy is one of the most promising method to study properties of hydrogen in minerals, but a complementarity use of other methods such as neutron diffraction will be necessary for thorough understanding of hydrogen in minerals.
