用Ａｒ￣＋激光器的５１４．５ｎｍ辐射做激励线采用９０￣°散射法测定了七种硝酸盐样品的拉曼光谱，给出了拉曼散射频移和谱线相对强度的实验结果
Excitation lines of 514.5 nm radiation with Ar ~ + laser were used to determine the Raman spectra of seven kinds of nitrate samples by 90 ° scattering method. The experimental results of the Raman scattering shift and the relative intensity of the lines were given
