中文摘要：
利用532 nm的脉冲激光进行了水的受激拉曼散射研究.水的低激发光能量下主要表现为受激Stocks和反Stocks 3426 cm~（-1）谱线;在能量大于140 mJ时出现低频率313 cm~（-1）受激Stocks谱线,同时出现后向3389和3268cm~（-1）的受激Stocks谱线.实验结果表明,在较强的激光作用下,水的结构表现为冰的Ⅶ相.
英文摘要：
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 iceⅧ.
