Stimulated Raman scattering is studied in liquid water using pulse laser at a wavelength of 532 nm. At a lower excitation energy, Stokes line and anti-Stokes line 3426 cm-1 can be observed in the forward Raman scattering. When excitation intensity is increased to 140 mJ, the low frequency 313 cm-1 line in the forward Raman scattering can be observed, and the 3389 cm-1 Stokes line and 3268 cm-1 Stokes line in the backward Raman scattering can also be observed. The experimental results demonstrate that the structure of water under the action of the intense excitation energy is similar to that of ice Ⅷ.
