Interpretation of Raman spectrum of Natrite (synthetic)

For natrite, the most intense Raman band, corresponding to the ν1 symmetric stretching vibration of the carbonate group, is at 1080 cm-1.

The 1429 cm-1 peak corresponds to the ν3 normal mode and line of 702 cm-1 is attributed to the ν4 symmetric bending mode. The Raman spectrum of Na2CO3 shows only one line of lattice mode, at 290 cm-1.
