摘要
通过内标法测量了液体水的O-H弯曲振动模对514.5 nm激发光的绝对拉曼散射截面,由峰高强度比和积分面积比确定该拉曼带的散射截面分别为5.14×10-32cm2 molecule-1Sr-1和4.51×10-31cm2 molecule-1Sr-1,并对实验误差进行了分析。
The absolute Raman scattering cross section （RSCS） of the O--H bending vibration mode of liquid water was measured for the excitation wavelength 514.5 nm based on internal standard method, the values of RSCS calculated by peak height and integrated areas of this Raman band were 5.14×10^12cm^2 molecule^-1Sr^-1 and 4.51×10^-31cm^2 molecule^-1Sr^-1 , respectively, and the errors were analysed.
