摘要：

CO2 hydrate crystals with polyhedral facet were observed to grow from CO2 solution. For both CO2 hydrates and CO2 solution, raman spectroscopic analyses were carried out. Raman spectra of CO2 and H2O molecules in CO2 hydrate were different from those in CO2 solution. We presented an attempt to estimate the density of CO2 hydrate by the raman intensity ratio, and found that the densities of CO2 hydrates were considerably smaller than those used in some modeling studies.
