The Raman spectrum has been employed to discuss the explanation of the structure of water and the vibration of [PO3-4] tetrahedron of the turquoise from Hubei and Anhui province.The Raman spectra are resulted mainly from vibrations of water,hydroxyl units and [PO3-4] tetrahedron of turquoise.The 3 510-3 440 cm^-1 bands with the main Raman spectra peak at 3 470 cm-1 were assigned to the ν(OH) stretching vibrations and the 3 290-3 070 cm^-1 bands assigned to the ν(H2O) stretching vibrations.The bands observed at 1 200-1 030 cm^-1 with the strong peak at 1 039 cm-1 were assigned to ν3(PO4) antisymmetric stretching vibrations.And the Raman spectra peaks at 650-540 cm^-1 and 500-410 cm^-1 were attributed to the ν4 and ν2 bending vibrations of [PO3-4] tetrahedron,respectively.The spectra of the turquoise from different localities are basically similar and subtly different.
